This Starbucks probably has the worst customer service in the area, but I go here for convenience. Due to it's mass corporate-ness, all drinks taste the same at every location, so I'm willing to deal with some frowney people to satiate my green tea latte addiction.
They have a drive thru, but it's definitely a slow one. I always tip at least $2 at the window, and usually they just ignore me when I tell them to keep the change and walk over to their change jar. I don't expect balloons and ribbons or anything, but just an acknowledgement like at other locations would be nice. Most times I don't even know if they hear me.
I've never had a problem with the drinks here, they're always correct and hot. If you haven't tried their green tea latte.. do it! In the summer it's good iced with no syrup and vanilla subbing in as the sweetener.. mm.
