after I tipped the coffee barista with no acknowledgement from her. No problem, it's a crazy time, our minds are all a bit distracted these days. Then I tipped the same person a second time, no reaction. I know it's only $1 on a $2 cup of coffee but that's a 50% tip for 30 seconds work poring a black coffee. If every customer tipped you $1 that would be a pretty good shift. I'm just sayin, a simple thank you goes a long way.
