I'm generally in a foul mood until I get my morning joe. So when I hit my local coffee place (it's a chain, not S'B#$%), 15 mins after it opens, I'd expect everything to be all set for paying customers.
So when my coffee of choice is not even ready, and they don't get my bagel toasted just so (I do request), it's a bad start to the day - despite the well-meaning smiley staff.

What are your early morning gripes?
