I think my answer would be the same on the flip side. I am thanked when I am helpful. I know there are some days it's just a brutal session and I've pissed off my client, maybe out of necessity, but still... I don't expected to be thanked in the moment. Or days that I just KNOW that I've been off and not on my game. I think for me, I do like the genuine "thanks, we did good today". While any over all thanks is appreciated, there are days that I'm thinking "Ooh I'm sure there's a few other words you'd rather say right now"
