Most likely. I crossed a small border crossing when it was deserted and there was a little office/waiting room with the agent who was stamping passports. He requested that I pay double of what the visa normally does, I said no and he said that it might take a while to get stamped in as they were "busy".

Called his bluff and took a seat in the room, pulling out a book to wait out five very awkward minutes until he gave up and allowed me to pay the listed visa cost without any surcharges since it was pretty clear that he didn't have anything else to do

Probably would have made me wait longer if they usually processed visas in an area out of sight.

I hope that the crossing went ok!
