The 3% thing hit me on a $150 payment from a client in Berlin last year and I didn't notice for three months because my invoicing software didn't separate fees clearly. It wasn't until I did my yearly audit that I saw the pattern and realized I'd lost almost $50 total. What nobody talks about is that some processors actually hide these fees in the exchange rate too, not just a line item. I refunded the client the difference plus a little extra and they were cool about it, but it took some trust rebuilding. Nowadays I always send a screenshot of the fee breakdown with my invoices so there's no surprises.

Man, I told myself the same thing, called it a glorified multimeter with a screen. Then I used one on a buddy's Archer that was doing this weird flicker on the strobes and it caught a cold solder joint I'd been chasing for two days. Guess we're all hypocrites now, huh? Just don't tell my Snap-on guy I said that, he'd lose his mind.
