I got placed into a corner surrounded by everyone even though there were plenty of tables available in quieter areas.
I've usually found AYCE places to be nice food, but here everything looks really unhygienic and tacky.
I went to the toilet and there was No Toilet paper, luckily there was a tiny dreg left but I had to fish for it.
When I returned someone had cleared my table with my food.
Overall I had a really unhappy time and don't feel I shouldn't have had to pay, I barely ate anything anyway.
