t may have been more reasonable for a small, local restaurant to refuse the booking but it's harder to argue in the case of Pizza Hut.
Not necessarily. Pizza Hut is a franchise. So at this particular one, a small lunch take may make massive differences. Which is probably the reason the rule about large parties was put in place.
I used to own a restaurant and have worked for Pizza Hut. On average, Large parties tend to stay longer and spend less per head. Which is why lots of restaurants don't take large bookings at their busiest times.
I definitely think allowances should have been made for the carers. But anyone booking a table at a restaurant has to follow that restaurants booking rules.
Had these all been non disabled people they wouldn't have taken a booking where 50% weren't eating. That's where, imo, the discrimination could be placed.
No one has a right to eat in a restaurant at a particular time.
