Getting pissed on the waiters who made you wait forever just to get
your order? I suggest that they put up a touch screen menu on each
table so that your arms won't get tired waiving on the waiters that
don't get your attention after a few minutes. All they have to do
after you pressed your orders, is to serve whatever food that you
want.
