Bring your own tumbler and pay less at Starbucks
Ahoj, coffee lovers in Zug (and i supppose in the rest of Switzerland)!
Freshly spotted this morning on the Starbucks-Metalli window:
Help Starbucks reduce its waste production by bringing your own tumbler to get your coffee instead of using a one-time paper cup, and save 0.80 CHF on your beverage!
I was told the initiative was already on for a while, but nothing better than a good layer of communications to raise awareness and get everyone involved.
