The ladies working at this particular Starbucks were pretty damn peppy working late at night (red eye) and mid-AM. A line with about 15 people in it, grumpy about their flights or having to pay for outrageously priced food (I fly first class, so this doesn't necessarily pertain to me) or their screaming child, these Starbucks workers had a smile.
The drink could have been a little stronger, but I know now to ask for another shot next time.
