It's possible Xander was doing research behind the counter. It's possible he was waiting for the latest episode of Supers to download and killing time by playing
Boomshine despite the fact that he knew staring at that thing for more than an hour was like inviting a cluster-headache in for coffee and doughnuts. Because he was dumb that way.
At least he made sure the
