Bringing your own is a health hazard. It spreads germs all over the equipment.

When I bring my thermos to a coffee shop, brew the beverage in their own mixer before pouring it in my thermos. There is exactly no contact between their equipment and my container, beside the barista hands (which they should periodically wash anyway) and between the butt of the thermos and the table. Also most of them give the thermos a few rinses & wash with the soapy water jet thingy before pouring.

I'm assuming you are much more conscious about this issue than I am (that's fine btw, people have various levels of germophobia) , but practically my whole office block do this without any noticeable health epidemic.

Also standard coffee shops (the Starbucks kinds) always have industrial scale utensil washers that rinse boiling water/UV radiate the utensils. Assuming a government issue the appropriate law, the coffee shops will be able to ensure your container hygiene just fine.

I think you and your environment are very different from the average consumer. At least in the office there's a shared community. I think you'd shudder to see what comes to the Starbucks/Dunkin drivethru.

		true, but the starbucks etc. scenario was already answered above. personal cups shouldn't contact cafe equipment. although i trust peet's/starbucks and not dunkin to actually follow it.

I don't mind the downvotes but, what? No responsible company is going to want a bunch of unused cups interacting with their gear.
