1- you ask for a certain bottle of wine and the waiter suggests an alternative as a much better match for your meal, you take their suggestion and find out that it is 3x the price of the one you selected (Hilton Auckland) - this smacks of sharp practice to me

2 - Mandatory service charges on already expensive wine with a hefty profit margin on it (i.e. the owner CAN afford to reward the staff for selling it)

3 - Padding of the menu ( this dish comes served with delicious roast ...) I should hope it's delicious

4 - 15% Service Charge added and then staff says what about the tip?

and on a lighter not no serious note

5 - The inverse naan bread law. If 4 of you each order a Naan bread in an Indian Restaurant then they will each be size of a table. If, however, on the next occasion you chose to order 1 and share it will be miniscule
