Shower

You decide that you need to go out for a meal before work, so you decide to grab a shower. As you take off your 'normal' clothes, as opposed to the stealth clothes you need to hide at night, you think about your last mission, where you almost got caught. Only your computer skills got you out of there safely, by screwing up their camera system.

You get into the shower, and turn on the water. It flows for a few seconds, barely hitting you, then stops. You mess with it, with no change. You walk out and grab a tshirt to cover up with, long enough to cover everything. You call the desk, and they say they will send the handyman there immeditely.

5 minute later, there is a knock at the door.
