not setting foot in that resturant ever again

My husband and I plus 2 of our friends went to wimpy on sunday.we were qued by a waiter who told us that he was going to call our waiter.it took her 15 min to get to our table.we ordered drinks and food at the same time.20min later we got our drinks,but she had forgotten my friends drink.when she brought the drink she then told us that they did not have peri peri sauce( we bought 2 peri peri half chickens).this was 35 min after we had ordered.we told her to cancel our order.she had a stinking attitude.the manager brought our bill and didnt even bother asking us what happened.we told her what had happened and her answer was \ your waiter must have been sleeping when we told waiters that peri peri sauce is out of stock.the manager was very cold and not apologetic at all.we paid for our drinks and left. this was not the first time I got bad service at this restaurant.a month ago when I was there I was given an expired brutal litchi.when I complaint to the manager his response was"did it taste funny\"". He then blamed their supplier for not unpacking the fridge"
