Upsetting for sure. Especially when we all seem to turn the other cheek in one way or another in order to avoid confrontation or making things weird. People should be called out when they do wrong.

Something similar happened to me about a year ago where I agreed to a price over text..drove an hour...got to residence...

Seller said everyone's downstairs...what do you mean everyone's downstairs?...Seller said I thought you guys could get into a bidding war for it..

I round a corner where 5 guys are surrounding a machine....I'll take it says stranger danger #1.

I turned to the seller and said give me $50 bucks for gas...He laughed and said yeah right....No seriously, 50 bucks. Dead silence. Guy buying had already given the seller a wad of cash. All I have is 20's says the seller...

I grabbed 3 20's out of his hand and said thanks for the TIP while exiting the same way I came in.

Was definitely upset and it took the entire drive home to relax but Couldn't have felt more satisfied in knowing I didn't let the seller get away with bad behavior and disregarding other people's time. Well...I guess I could have grabbed 3 hundreds instead. Maybe next time.
