My American life is mostly focused in Hawai'i; everywhere else I visit on the Mainland is for Business Trips, so my attention is divided on the work at hand.
In Hawai'i I did not see as many Convenience Stores; Seven Eleven was around but there weren't visible Competitors so the scene isn't as prolific as the Japanese Holy Trinity of Seven Eleven, FamilyMart and Lawson seen at every block. Plus AEON.
In South East Asia, there are also just as many Convenience Store chains and the biggest difference is that every Theft they have is directly deducted from the pay of Staff who were working that Shift.
I've seen plenty of things during my stint in Retail Management, but seeing Young Cashiers literally cry their eyes out because what little they make gets cut for Theft is still up there with the worst.
So that's what I can contribute from the other side of the Counter.
On a lighter note, I've also seen Warehouse rats choose which Imported Milk they want to drink, but it seems Off-Topic and a story for another time ...
