...I'd really like to start a list of the Top 10 ways to really piss off your vet (or at least really annoy the hell out of them). Whenever I get around to it, me thinks this one should be on there:
Being late for an appointment is annoying, but too common to make the list on its own. But walking in 30 minutes late for your appointment on a busy Monday morning (packed full with one or two emergencies on top of my regular scheduled program) with an extra dog because you'd really like to have BOTH of them "checked out", is a sure fire way to get on my bad side.
Oh and complaining about the wait isn't going to make me get to you any faster.
