Loch Fyne - Milton Keynes

Unfortunately on this beautiful night celebrating life and writings of Robert Burns I am not sitting among fellow patrons of Burns's poetry and Loch Fyne fine quisine, but rather writing this sad tale of Burns Night.
That's started on 14th of December when on my way home I bobbed into Loch Fyne Milton Keynes and seeing announcement of Burns night booked a table for me and my wife. No deposit was requested and being a regular I was warmly greeted by a member of staff I am familiar with. That was the last nice part of this tale.
Today on 25th of January I rang Loch Fyne Milton Keynes at around 6pm to make sure I remember the time I booked this table for correctly. Uncharacteristically for Loch Fyne Milton Keynes I was answered by a young lady that introduced herself as Emma and with no pretence for care or actually checking informed me that I was not on the booking list.
When I suggested double checking this the young lady in question with mechanical perfection suggesting a long practice pretended to check for my name first on hard copy and then on computer. Amusingly she didn't realise that a phone connection was good enough to allow me to hear that wasn't doing anything she impyed. I could clearly hear people talking around her and on the street near the entrance (her station is right in front of the main entrance). What she wasn't doing was checking in any kind of papers or computer terminal.
Annoyed by this cheerful lack of customer service I asked a number of questions of the nature how can I verify that I indeed booked the table. In a same automatic answering machine manner I was informed that "the only way to be on the list was to be on the list because everybody who booked and paid deposit was on the list" - end of quote.
May I remind you, I wasn't asked for any kind of deposit. Furthermore deposit wasn't suggested on the announcement.
At this point after not seeing any attempt to resolve situation and hearing "I am sorry, I don't have you on the list anywhere" in a very annoyed tone that implied without any shadow of a doubt that I should stop wasting important people's time I hang up after suggesting improvements to the booking procedure were needed.
My wife only heard my side of the conversation and being kind soul that she is assumed that there was some kind of misunderstanding. She called the restaurant's number in about five minutes or so. Upon trying to explain the situation she interrapted midsentence by the same "helpful" young lady and subjected to a brisk talking at for lack of manners of her husband. I know it is hard to relate such an elusive thing as a tone and general attitude of conversation in written word, but one can only think of American description I once heard overseas: "I don't give a **** and I know that you know that I don't give a ****, but I am saying "Sir" and "please" and "thank you" enough times so you cannot say that I am impolite". Only difference is young lady called Emma didn't really said "Sir", "thank you" etc. She just made it clear that she didn't give a ****.
The talking at my wife by said Emma among other things was build around the notion that she was working hard and trying to find a table for us when I so rudely hang up on her. I want to make it clear - nowhere during nearly ten minute conversation I had with Emma was it suggested, impyed or hinted then there was even a remote chance of anything of the sort. All through the conversation I had with her I was given to understand that the place was packed to the rafters and I should stop wasting her time, especially since I obviously didn't pay a deposit.
As I mentioned, my wife is a very kind soul. She doesn't scream at people, she doesn't yell at people, she doesn't shout at people - she doesn't say an impolite word. But at the end of being talked at by Emma she asked to speak to the manager. Without as much as taking a breath Emma said that she was a manager. And when asked to spek to the superior she also instantly informed my wife that she was indeed the owner of Loch Fyne.
After tonight's experience I simply don't know if I should bother returning member's club card or simply drop it into the garbage.
