I have a PO box, and when I check it I typically see the same 3 employees. I'm very respectable looking, not sketchy at all and I've gottem pretty familiar with them over time, is that good or bad for my opsec at the post office, or does it not even make a difference?
I think you pretty much answered your own question? You said you aren't sketchy and look respectable so why would they think hmm out of the hundreds of same people that come in here a day for their mail THIS PARTICULAR GUY just has to be picking up drugs. Cmon man use a little common sense here.
