I'm not sure if legally he can impose a service charge - does anyone know the law on this?
I don't eat in restaurants like this, but if I did, and I thought the service was poor, I would delete the service charge from my bill.
I only eat regularly at one restaurant, our local Italian and all tips are shared equally among all staff - waiting staff, chefs, the washer-up, everyone gets equal shares, which is only right and proper since they all contribute to the dining experience.
