Here’s something to lighten your day if you work in retail. There’s a site called Customer Service Wolf which posts comics about working in retail, specifically about a wolf who works in retail. I’ll spoil it a bit for you–most of the comics end in the wolf eating the customer.
And since there’s a lot of days when I’m sure you think about at least BITING an obnoxious customer, you can step it up a notch with Retail Wolf.
Go here to read the strips, it looks like they post a new one regularly.
