how stupid can one person be?

i've had some very frustrating days at work lately. people are impatient and we have a lot of new staff so it takes longer to fill a script than it really should. luckily there are some ridiculous people to make me laugh at my job, and a blog on which i can vent. here's some highlights:

(on the phone)
me: may i help you?
man: the viagra you gave me doesn't work. it is possible you gave me fakes or ones from mexico?
me: no, we get them from pfizer
man: who?
me: the manufacturer
man: the samples from my doctor always work, is there anyway you can test them?
me: no sir, we don't have the equipment for that. (here ends the conversation)

(lady in the store)
me: can i help you?
lady: yes, i need some crutches
me: we have some for sale, but we don't rent them (i pre-empt with this because most people don't want to buy them). they are just around the corner
lady: i want to rent some (what did i just say?)
me: sorry, we only rent them

we had an intern(she was in her last year of school on rotations) a few weeks ago, and she didn't know how to spell some of the drugs. on the left is what she wrote, the right the correct drug.
superdox=ciprodex
voltram=ultram or voltaren (we had to call the md)
methylin=medrol
atavert=antivert
once we ordered panera for lunch and she accidentally ate someone else's sandwich. she didn't realize it until it was completely eaten. the sandwich she ate: turkey. what she ordered: tuna salad.

we once had a lady pull up to the drive-thru to buy a cane. clearly this will not fit through the chute. people think they can get their pictures through the drive thru, too. and sadly, i've had people ask me how to use rectal suppositories (one guy was going to swallow it, i'm sure). perhaps i am being a little mean, (and i know i probably shouldn't have gone into retail) but sometimes i can't help it. and it makes me giggle, but it may only be funny to me.
