I know this looks like an April fool's post but I'm totally serious.

I frequently get custard at Culver's, and have recently started getting milkshakes. I like my milkshakes in **vanilla** custard with chocolate syrup. The first few times I ordered it this way, it was perfect, but now they say "ok, so a chocolate shake?" And I say "no, a vanilla shake with chocolate syrup" and they say those are the same thing, so I'm like whatever. I get a chocolate custard shake with nothing else in it. I can tell the difference because vanilla with syrup is a much different taste than plain chocolate custard. It also looks a lot different as well. This has happened 2-3 times now where I request vanilla with chocolate syrup and am given chocolate custard, and it's starting to get really frustrating.

If I *am* the ass here, how could I better explain it?
