Threads like these drive me mad, can we just be clear, there are two types of tight people:
Type 1
(Generally a lone wolf at the table)
The Penny pincher: when everyone at the table has had an equal number of courses and drinks, nobody has taken the piss, the difference comes down to pennies and someone is insisting on individual bills and it's down to nothing but tightness, everyone knows someone like this, they are annoying
Type 2
(Often several of these at one table)
People ordering expensive courses, extra courses, wines, beers, etc etc, a having a lovely evening but it's clear there are differences in the orders, some mains only/some not drinkers etc and type 2 proclaims "we split the bill" and even goes as far as to "not be able to bear" not splitting the bill. Type 2 is more socially acceptable than Type 1 but he shouldn't be, he wants others to subsidise him and pay for him, Type 1 is at least happy to pay his way.
Type 2 is the greater tight arse and often not a very nice person as they often infer people who don't subsidise are actually the tight ones
Type 1 - Tight
Type 2 - Tight and sneaky
There are other types of course (op's daughter Type 3 the person who speaks for everyone and insists a split, she's just rude)
