I can only sympathize, OP. I wound up having to ask my ex-husband to come get me. We are on fairly amicable terms (we have a 15 year old in common, so sometimes socialize due to him), but this wasn't an interaction with him that I particularly wanted. But the place said there was no other option than having a person pick you up, no uber or cab.
Sorry, just so as not to be misleading - it is possible that they would have let my son pick me up in an uber or cab, but he had school. I don't know either way on that one.
