Agreed! Finding a wrapper is a whole lot different then finding a condom.
You're daughter is only 2 so she'll never remember it even if you make a huge deal about it in front of her. What are you having her checked by the doctor for? Are you afraid she ingested something? If so, I wouldn't want to wait until the following day. Otherwise, what do you expect the doctor to do? Run blood work? That just doesn't make much sense to me.
BTW, your average hotel bed cover and TV remote is probably a heck of a lot "dirtier" then a condom wrapper.
Why do people always need to ask for something? Shouldn't a simple apology suffice in this matter? IMO, that's all you really deserve.
