Here is a protip: if you think the barista is cute, buy your drink and then ask for a special treat. If the barista looks at you weird, say "a sugary treat - a pastry" and show 'em the coupon from your phone. There's your in! I know you can handle it from there.
The coupon deal lasts only from now to tomorrow morning, 10:30am, so be sure not to miss it.
