Rant: I used compressed air backwards for 8 months at my shop in Tucson

So I've been blowing out dusty PCs and laptops at my repair bench since March. Every single job I'd grab the air duster and spray, thinking the little red nozzle was the output. It is NOT. Realized last Tuesday when I went to clear a fan on a customer's HP and instead sprayed a blast of freezing liquid all over the motherboard. The customer just stared at me and said 'uh, you know that's the intake, right?' I honestly never looked at the can label. Killed a perfectly good GPU because I froze the thermal paste solid and it cracked. Now I check every tool like it's my first day. Anyone else have a tool that made you feel like a complete rookie after years in the field?

Wait, people actually freeze GPUs with those things?
