I've been doing these health and safety checklist audits at a major electronics retail chain for months, and the scheduler has always e-mailed me to ask which ones I want to do for the next month. Well, this time, I replied with my desired dates less than 20 minutes after the scheduler e-mailed me, and they had already been taken! It would have been a nice courtesy for him to ask an experienced shopper first, as I've been doing them nearly every week for months...
