Oh man I did the exact same thing at a Starbucks last year, logged into my bank without even thinking about it because I was rushing to pay a bill before the late fee hit. The barista probably had better things to do than snoop on my sad checking account balance but still. The VPN thing is real though, my brother set one up on my laptop and it scrambles everything so even if someone is watching they just see gibberish. It's not perfect and some free ones are sketchy but the paid ones actually do what they say. Better than my old system of just hoping nobody at the next table cared about my Amazon password.

Feel that pain, wrecked mine the same way once.

All due respect to the old timer but that demo hog was probably chilled and settled just right, and a paying customer's order on a random Tuesday is a different animal. A sharp saw used right does not cost you yield, sloppy knife work does, so blame your technique and not the tool.
