I'd imagine there's a lot of walking involved; maybe biking if you supply the bike.

WalMart used to (and may still have) a policy where suppliers and business partners used to have to call the corporate offices in advance to get approval to send a fax before WalMart would turn the fax machine on to receive it. They must think that their employees aren't very valuable if they think it's worth wasting ten minutes of their time to decide whether or not to allow a one page fax. Any place that values a piece of fax paper more than an employee is a place I don't want to work.
