That's just as painful with good relative pitch. :-D I dropped out of a choir largely because the director put up with (or didn't notice) some pretty bad flatting. This was an otherwise superb choir, who has been to national ACDA conventions multiple times. My other choir (a semiprofessional chamber choir) sharps occasionally (especially with songs in the key of F), but never flats.
