You do realize that some guild groups will vote kick even if you do nothing wrong, right? It could be a piece of loot they want off a boss, and you might need it too (or they'll assume you need it).
Also, he said "one sec" and it only took him a minute. That's not being rude, that's asking his group to wait a freaking minute.
This bug is definitely fucked up. The 15m alone is bad enough, but making it 30 ON TOP OF the time it takes to queue up again (as DPS... ugh) is mind-blowing. That's anywhere from 45m to an HOUR.
