When I worked at convenience stores, 3rd shift, I always offered the police officers their coffee for free. I never had one accept that offer. I was actually very impressed by their professionalism in declining “perks.”
Perks! HAH! I don’t who y’are, that’s just funny...
When I was waitressing, we always made LEOs, EMS, firefighters etc priority customers, if they were in uniform. Very seldom would other diners make any mention of it. Just made sense. I never offered freebies to the guys, any more than I did for other diners—ie, food discount if they’re order was somehow prepared wrong, that kind of thing. Smae as I’d do for any diner.
