Stop in for a cup of coffee

And a step further I've been at Lowes, Walmart, barber shop, middle of the day and run into people in uniform. I'd never, ever, thought of doing that. That's what off-duty time was for.
I'm with you, that's the best policy. With NPS, lunch is unpaid, so its our time, - usually its only a 1/2 hour. Vehicles, that's a different story - only allowed to stop at places that were on direct route between units that you had business at, even on lunch.
