Bare Essentials of Confirming a Booking

I just got back from a wonderful trip to Florida. The night before I left, I received a call about painting at a day camp the day before July 4, for up to 120 kids. My plane left the next morning and I had already decided that there was absolutely NO time to lay down and try to sleep that night (work all day, then packing, prepping for leaving the kitties, etc.). So I got some Dunkin' Donuts coffee with the espresso shot in it, and went on a whirlwind like in the old college cramming days. At 4:30 a.m., I finally composed and sent the proposal/bid to the lady, with sample photos, etc. Then off I flew to the land of alligators (we saw a 14' long one by the roadside).

Anyway, most of the trip passed without a call back, so I assumed that it might not be a go. But a few days ago, the lady called back wanting to book, and so I returned her call on my friend's cell (I don't carry one), and then the whole next day, did not hear back from her. I was set to fly the day after, so I gave it breathing room and planned to call her the morning after I returned.

So yesterday, an hour before I was to leave the resort for the airport, I was STARK NAKED in the bathroom, ready (at that very second) to step into the shower, when my friend knocked at the door, handed me her cellphone, and said it was the lady.

Stifling a big laugh, I took the phone and, as is my usual way on the phone, paced while talking in a big room full of marble surfaces, hot tub, mirrors, etc, speaking as if I was fully dressed and at my desk.

I did get the booking, and it is a nice little bit of money which will replace the cost of the pet sitter for the ten days of my vacation, and, it was not a raw deal. I just made the deal in the ... raw.

I love vacation.

I love being back.

I love face painting.

But you can be sure I will be dressed when I show up at camp next week.

So do I need to write in a clause that I will always be fully dressed for my gigs at can I just assume that they'll know that in advance?

Article 6
   Clause C.
         Artist will arrive fully dressed. Should artist     arrive in his/her birthday suit, please kindly whisper in their ear they may have forgotten something.
