So I had someone walk up with 6 6-packs of sodas and say "Alright I need you to help me figure out this app so I can get the lowest price"
Pulls out her phone "I don't know how to work all this technology."
I get her to the app she apparently didn't know she already had and I tell her she has to log in which gets the explosive response "AAAARGH A PASSWORD! Everything needs passwords nowadays, I hate it!"
Goes on and on ranting about this while I scan stuff and think (Do you complain about every door having a key also?)
