Don't order a "random assortment" ever again.
No one likes plain donuts. Absolutely no one. And sure, some people have the occasional favorite oddity like Bavarian Creme. But trying to guess the weird ones for each person in your office will only leave you with a half-full box by day's end.
Here's the reality. The 'average' person prefers a chocolate donut, statistically. So at the very least, if you're in a hurry, order "a dozen random assortment of chocolate donuts."
