At most Accelerator glances down a little when his shirt is grabbed, though since he's used to Last Order doing that sort of thing he isn't bothered. The person at the cash register gives them a bit of a look, but she isn't being paid enough to care so she takes the order and gives Donnie the pineapple without any issue.

Their food won't take long to be made, and when it's ready Accelerator will grab it and lead Donnie over to a table. Once he's sitting down he's switching his choker back to normal mode to preserve the battery.

This could be going a lot worse, he supposes. After Donnie eats he should probably try and contact Leo, and just hope he hasn't become child-sized as well.
