I'm not a Starbucks barista, but a local coffee shop barista and second that we appreciate ANY sort of tips at all!
Do any of you complain about tipping a bartender?
Barista=Bartender.
I've never heard of anyone complain about someone opening a beer and handing it across the counter getting $1 tip, but I've heard of baristas who have been told a ridiculous paragraph-long order specifying milk type, foam/no foam, # of pumps of flavor, serving temperature and what not, getting slammed for hoping for a $.50 tip.
Doesn't make sense to me.
Also know that as a barista, your job is not just "pouring black coffee into a paper cup". First off, that black coffee is high quality beans that have been roasted right there and came straight from the coffee farmer himself to give YOU the best cup of coffee possible. Not just some Folgers coffee that you can buy that's been sitting on the shelf for weeks. That coffee took lots of work to get to your paper cup.
Secondly, as a barista you aren't just making drinks and doing your best to keep customer service high.
You are washing dishes, cutting & making food, sweeping & mopping floors, cleaning bathrooms, washing windows, ect. You are a janitor 90% of the time and a barista the other 10%. Janitors start out making $15/hr when barista's don't even get paid half of that.
Overall- Notice the small things. If the tables are wiped off, the bathroom is clean and stocked, your black coffee in your paper cup taste good, know that it was those baristas behind the counter who did all that to make YOUR experience better.
If you appreciate any of that at all, a $.25 tip wouldn't be so bad now would it?
