It's a little more difficult to dispute an ATM transaction given that these ATMs offer a way to decline DCC (and the cash & balance scam), which I detailed in
this post. You can still try to dispute the transactions, but I suspect a company such as Euronet to vigorously contest any disputes.

I'm pretty sure even if that's the default there is a way to bypass. It's only $5 dollars (3.5%) but it's the principle of the matter and the waitstaff was all snooty about it.
File a dispute per the normal process with Chase. As I said in my previous post, at ~$5, Chase is unlikely to file a chargeback and simply credit you the money you are out. This further proves my point in cases of known forced DCC that it might be easier to use cash to avoid the situation. The staff were lying, of course, and the fact that you were in a rush didn't help attempt to resolve the issue at the time of the transaction.
As a best practice, I also look for merchants where there are customer facing credit card terminals. In cases where they hand me the terminal, I hold onto it until the receipt prints, showing local currency.
