Mike follow this advice
Get a group of people book table order plenty of food DO NOT ORDER PLENTY OF ALCHOOL make sure that each person leaves an amount of food on their plates complain after starter course, continue to main course leave a small amount again, complain again. do not ask for the bill wait to get it.
Refuse to pay bill DO NOT LEAVE THE PREMISES normally they lock the door and just let the other customers in and out MAKE SURE EVERY BODY IN YOUR PARTY HAS THE FUNDS TO PAY ON THEM and remains polite & calm
Wait for the police to arrive be polite and explain the reasons why you are not willing to pay
EXAMPLE several of your party have found hairs in the food, make sure other people in the resturant can here whats going on, explain you are willing to take this matter to a civil court. THATS IT POLICE WILL NOT BE INTRESTED OTHER THAN TAKE YOUR ADDRESS
As long as you entered the premises with the funds to pay & most important the intension's of paying
and you do not leave the premises you have not stolen anything the moment you leave, this is theft. YOU WILL HAVE TO PAY THE DRINKS BILL SHOULD THE POLICE REQUEST YOU TO DO SO.
Been there got the T-SHIRT
