I've never known the stereotype that bakers are dumb, but this is a good piece of evidence to prove it. I bet there was a long discussion in the bakery about why someone would want "Olympic Rings" on their cake. No one at any point thought, "this doesn't make sense. Let's call the client and see what's up." Let's face it, most people just aren't very smart. Or the person is smart enough, but not at seven dollars an hour. At seven dollars an hour, you get the dumb version of me.
This is obviously a cheap cake, but have you seen those fancy cakes that have moving parts? I can't begin to imagine how you would make one of those. No wonder they cost an arm and a leg. That's a skill only a few people can do, and even then, they struggle with it.
