How about this:
In Café Grumpy in NY customers cannot get a coffee to go unless they buy the porcelain cup. I quote the NYTimes:
“You’re supposed to drink espresso fast,” said Caroline Bell, an owner of Café Grumpy, explaining that paper lets the heat dissipate too quickly.
When some customers at the three outposts in Brooklyn and Manhattan became, well, grumpy over the lack of takeout espresso, Ms. Bell instituted a policy meant to be taken more with a wink than with the snarl of the cafe’s logo: Patrons can get an espresso to go, if they pay $12 to drink it from a porcelain cup they can keep. “People actually do that,” she said. “There’s a guy that comes in every day to Chelsea with that cup and gets espresso.”
