I feel like a chump every time I tip the sales guy at the weed shop down the street. Gosh, thanks for telling me that a sativa is gonna be a more cerebral, energetic high and an indica more of a relaxed body high. I'd never heard of marijuana before today and my phone doesn't have Google.
Bonus points this time for not knowing they were out of something in a display on the counter and especially for mumbling "Thanks" as he turned away and rushed back to sit down with his friends before I had finished the transaction.
I'm old, I'm grumpy, and when I was young and stoned off my tits doing customer service, I crushed it every day. Be better or you will not get my $6.75 next time, sir.
