Disgusted by Hungry Lion

I am utterly disgusted by the service I received from Hungry Lion Lansdowne Corner.I went on the 26 October and stood in a queue to buy a meal for my girlfriend and I. When I was finally third in the queue(after waiting quite a while)we were told cash only as the tills wasn't operating.I had to leave the queue to get cash only to stand in a longer queue.When I finally got to the till I couldn't use my voucher and had to pay full price for my meals.To top everything off my girlfriends burger was dry and didn't have any sauce.The staff also gave attitude when asked for the managers name. Bad service really
