A group of friends went to a newly-opened Italian restaurant in a village.
We ordered drinks and starters, and that was OK. Then we ordered mains. The wait was ridiculous, but as a group we were chatting happily and ordered more drinks.
When the mains came out several were wrong. A few people accepted the alternative, but one person hated fish and wouldn't accept the tuna alternative to the chicken dish he'd ordered. My vegetarian dish didn't turn up (I wasn't vegetarian but I often eat meat-free). They said the chicken meal and mine would be with us ASAP. Everyone else started eating. Nothing was fantastic, but it was edible and we did speak with the manager and make it plain that the food was sub-standard.
About 40 minutes later our meals came. Mine appeared and tasted like a few vegetables in a few spoons of ragu sauce. My pasta however was so overcooked that it was bloated, and couldn't be picked up as it fell apart. Inedible. I sent it back and declined an alternative.
So we ordered more drinks, and decided that we'd have desert to finish off. Most of us ordered the chocolate mousse. Bad choice. It had been made with raw egg, which had separated. So we ate the slightly thick non-moussed chocolate, and then found a pool of raw egg white under. Bleuch!
When the bill came I calmly crossed off everything that had been inedible, and then put an alternative costing against sub-standard food so we made our own deduction. We wrote out a cheque paying for all drinks, the starters, the edible mains, the couple of edible desserts and a reduced price for everything else. On the back I wrote my name and address and why the cheque didn't match the bill.
The manger threatened to call the police and I said that would be fine. We were not stealing as I'd left my address and she was free to take me to court for the rest of the bill. I suggested she look up consumer rights and I worked in a restaurant myself and knew I was allowed to do this. The other tables in the restaurant seemed to take note of my comments.
It closed a few weeks later.
