ilogical resteraunt menu
Kerlin:
Went to a pub, wasn't aware my programmers mind was switched on, read the menu .......Fish with chips and salad or vegetables.
Some one asked can you get chips with vegetables, I checked again and I saw ....Fish with chips and salad, OR vegetables. so I said no you cant.
Because logical complements ( not ) are performed first, logical conjunctions ( and ) are performed next, and logical disjunctions ( or ) are performed next.
Cash register operator said Yes you can get chips with vegatables, so menu should read...........Fish with chips, AND salad OR vegetables.
DOH, Suddenly realized I was thinking in Boolean without even knowing it and went into an LOL when I realized it.

Hehe, just had the same thing happen with a credit card.
It was $5, and terminal menu said PIN OR ENTER
So, I did exactly what it said, and just pressed enter. 8)
It failed, turns out that really mean PIN THEN ENTER ( or PIN AND ENTER)
brucehoult:
Usually that means in you don't have a PIN then you press ENTER and sign instead.
Weirdly, most shops / machines in the USA don't accept PIN verification even when your (foreign) card normally uses one.
xrunner:
Went to buy some things at Home Depot. At the self checkout I scanned it all and then the option is presented
"PAY NOW"
I asked the lady monitoring the self checkout "Do you know who NOW is? I'm supposed to pay them, but I can't find anyone named "NOW" ???
:-DD

Yeah here in the US we don't use a PIN for a POS credit transaction, only for debit transactions. And a VISA or MC network debit card can (in most places) be run as credit/signature without a PIN, but the PIN is required if you're getting cash back. The annoying thing is different POS terminals handle this differently -- some expect you to hit ENTER to run a debit card as a signature transaction while others expect you to hit X/CANCEL to do so. At new terminals I inevitably hit the wrong thing and have to start over, LOL.
