Same I’m a hard ass when people start pissing around on prices.I agree- I do lots of bst and I don’t piss around with scammers. I will sell to them but I make sure I get my money before anything gets transferred over. Often you know who the scammers are if you have your wits about you.
I was once so mad when someone showed up and pulled the I only have this much cash on me and I have to go to the atm that I told them I’m sorry I’m firm on my price and I don’t have time to wait around for them to go to the atm and i “went to work”.
the other one that gets my goat is the “what’s the lowest price you’ll do”.
I’m much softer and more free with selling when people don’t haggle, when they just buy what they want for normal price I always throw in freebies, I also offer up replacements of fish that die on them for whatever reason
