Why would they? At Waffle House, that is just another minute between 0 and 59. But of course we are assuming that he teleported to the back of the line.

Isn't teleportation inextricably linked to time travel (to the extent that either one is actually possible)? My point being that the staff might not remember him yet.

He claims in the article to have teleported twice which means that he could have teleported to a future waffle house (maybe even one that has not yet been constructed) before teleporting to the present.
