I think the guy was just ticked off at something (or someone) else and took it out on the pharmacist, which happens a lot, here. Lots of entitled foreigners in a sanctuary county makes for lots of rudeness.
Wow. Bill the Son? Up and out to the gym? Is he ill? Oh. Wait. New Year’s Revolution, right?
I don’t know what has happened to Bill (except that, with Tom home, hanging around his room is suddenly less appealing). However, I’m thrilled that he’s voluntarily doing daytime-hours activities.
