there's always chances of the food quality being different
during the food-tasting session and during the actual banquet
the hotels can do many things to "compensate"
like offering 1 free table, 20% discount.....
or give them vouchers for hotel stays or restaurants
(though usually, with the bad experience, ppl wun bother to go
back)
it may be rather unreasonable to not to pay the balance at
all
2 dishes not up to expectations but the rest was happily
consumed, rite?
we do not know how bad is the bad as we oni have this side of
the story
