My favorite is the local tax office charges extra for paying online vs going in to the office to pay in person. At first, I thought it was a way to recoup the processing fees as you're obviously paying by card online. The last time I paid in person with a card, that fee was not added on though. So they are charging you extra for not having to pay an employee to process your account.

I looked at buying tickets for a local hockey game last week, and the venue goes through Ticketmaster. The service fees were exactly the same as the actual ticket cost, maybe the total 200% of the list price.

I ended up going to the physical box office, where they still charged an extra 40% of the ticket cost in service fees.

The one that pisses me off is when the waitress tells you to pay with your phone, and it's charged a "convenience fee."

usually the service fee doesn't even get refunded, which feels additionally foul
