"it's seriously really fine, I can deal with it"
he pulled out some money
"how much does it cost?"
you could see the pain on his face even if he tried to seem like it was fine, he gave the cashier some money and apologized for the inconvenience, just as he did that he very clearly stumbled back a little and looked at his hands which were visibly shaking
"shi-"
he caught himself and looked around
"ha ha I should probably wash my hands."
