Then this is what they should do:Provide reusable travel mugs for their regular customers. And then, when you go back the next day, you could drop off the dirty mug and get your coffee in a new, clean mug. With a 10 percent discount, of course.
Because really, cleaning those narrow travel mugs and all their switches and nooks and crannies is not pleasant. It's why I never use them. But if I never had to clean a travel mug, I'd happily use one every day.
