Father's Day

A friend reports:

I am in a house with broken air conditioning, with my in-laws (actually, it might just be hell and I'm unaware of it). At brunch (there were 12 of us) my father-in-law waited until everyone was getting up from the table, then collected the half-finished cups of lemonade and orange juice from around the table and proceeded to drink them all. I would suspect mental illness, but am confident the real reason is cheapness.
