This was during 30 minutes of a session:

(I flop 2nd nut flush draw on flop and hit my flush on the river.)

Table Coach: sucked out on the river again.
Table Coach: you guys are all terrible
Table Coach: hero, keep playing those longshot draws and sucking out.

(I win several more hands during the next 30 minutes...)

Table Coach: I cannot believe how bad everyone at this table is.
Table Coach: everyone except hero.
Hero: Wha, I though you said I was terrible and that I played longshot draws and sucked out all the time.
Table Coach: well, after watching you for a few hands, I changed my opinion. Can you believe how bad everyone else here is?
