TGI Fridays

Me and my girlfriend came to eat at this restaurant which we have never eaten before, and after we finished our food as we're waiting for our waiter to collect our payment we see a quarter sized cockroach crawl under the table acrossed from us which was just disgusting to see especially in a restaurant. When the waiter came to pick up our payment I told her just like this "I know I ate all my food already and dont mind paying for it but i just want you to know that we just seen a cockroach crawl under that table right there(which was the table acrossed from us)" and her response was "yea we get them in here sometimes its an old building but it doesn't interfere with the cooking part of the restaurant", umm no matter if it interfered with the cooking part or not nobody wants to finish eating, during eating, or about to order food want to see any bug of any kind especially a cockroach crawl on the floor right acrossed from them. My bill was $25.20 and to be honest at that point they should have just given me my food for free.
