This is interesting.
And for the love of God, people, I'm trying to get you your drinks in less than a couple minutes. Your sandwich is being made by someone else twenty feet away from me. Why on earth do you expect me to have you a hot grilled sandwich ready to go by the time I hand you your drink? How many places do you go where you don't expect the drinks first? If I held your drink for the minutes until your sandwich was ready, not only would I fail all our benchmark tests, you'd be even more pissed off standing there without your single-shot extra-sweet nonfat extra-whip white chocolate mocha with a pump and a half of toffee nut. Try waiting five minutes. If your sandwich has been more than eight minutes (enough time for two full rotations on the grills), then let me know, by all means. Haughtily informing me that you also had a food order when I hand you a drink is going to get you polite explanations of the process and apologies that you might have to wait 45 more seconds, but it's not going to endear you to me.
