My local Starbucks offers a 10 cents discount and extra loyalty points for bringing your own cup. I've started bringing an insulated one that keeps coffee hot for longer & doesn't sweat with an iced beverage. I seldom see others bringing their own cups, even regulars I see there every week, even when Starbucks themselves sell reusable cups. It is almost like there is a weird stigma about handing the barista something that doesn't come from behind the counter. I encourage trying it, especially if you visit the same coffee shop habitually like I do.

I wonder how much of it comes down to inconvenience. I've been bringing my own thermos for a year or so now and it took me some time to get used to the ritual of scrubbing it with soap and a bottle brush after use every day - at first I found it inconvenient enough that it made me want to just get paper cups.

Now it's a nice little ritual and I am used to the advantages of bringing my own insulated container with a lid - I can carry it back with groceries or do other errands without worrying about my drink spilling or getting cold.

FWIW I do occasionally see other people at my local coffee shop show up with their own mugs, but I agree that it's quite rare.

To be more effective, all drink prices should be reduced by 10 cents, then a 10 cent surcharge added for every disposable cup. The price remains the same for all customers, but the extra line item reveals the external costs.

If I'm going to use my own cup I just bring coffee from home in it.

Personally, when I get a coffee to-go, I want a disposable cup so that I don't have to carry it around for the rest of the day.

[andreimackenzie]

Fair enough. I use plenty of disposable stuff in other contexts.

The habitual part is what makes a difference for me with my local coffee shop. I usually walk over around midday when I WFH, mostly to move around and re-energize for the second half of the day. Since I know I will be coming right home after, it is easy for me to adjust my ritual to include the cup.

Bringing your own cup is also healthier, because paper cup linings are made of plastic that when exposed to hot liquids are likely to turn into microplastics.

My rule is: 1) keep hot stuff away from plastic, and 2) assume everything is/has plastic unless you know for certain.

Reusable cups might be healthier assuming regular cleaning in the bottle, mouthpiece and lid.

I would hope it's a health code violation for a food processing employees to handle something given to them by a customer while processing food without either changing gloves or washing hands.

I think the habit/friction part is underrated
