I have spent nearly 1000 pound in this bar tonight to have the last drink I purchase given to another table. Once I questioned the management to be told its my fault. As there have been multiple people on our table.
Have spent this kind of money in here multiple times with work. Management are dismissive and rude instead of replacing 12 pound of drinks they lose a continued custom. Disgraceful. I would have paid to have the drinks again just to have the drinks but no offer of replacement was ever made.
