A few sessions ago there was some sort of confusion on his end about how much he was supposed to charge me that day (apparently due to lack of sleep and over-caffeination) and he had to run my card twice since he undercharged me at first. It took several minutes to get all this sorted out and once I had paid and everyone got situated he opened up with "Okay, talk", which really amused me. Much better than "what brings you here today".
