Visited Braintree's Prezzos with 15 others at lunchtime. Service was excellent and everyone got their food at the same time, piping hot. But why oh why is a 10% service charge added because there are more than 7 people at the table? It's optional but appears on the bill and cannot be left off and when paying the cashier makes the point that the bill is being paid without the service charge. As it turns out they received more than a 10% tip. It just seems morally wrong to add this automatically, presumably in the hope people will not question it.
