I disagree with your work ethic.

Arriving at a restaurant to then leave after seeing a better offer is terrible work ethic. Sure you'll get the better deal but what about the business who pays for the privilege for us to deliver for them?

How would you like it if you had a family owned cafe that had a driver suddenly decide "nah, fuck it bye" as you're about to hand over an order. I'd be pissed too.

Again with the super market - you know they CAN be big and you accepted the informed risk. You could of got roo to split it but you buggered off instead.

Absolutely abysmal and selfish work ethic. I feel sorry for whoever employs you into their company.
