The shorts

You'll be exposing something sexy no matter what you choose. So, why not the shorts? You remove them and stick them next to the shoes in your car. You approach your next customer with your panties showing. This time, it's a man in his 20s. He opens up and is surprised to see a girl with only black panties covering her nether region. He asks "Did you forget part of your uniform?"

"No, I just got pizza sauce on them. I figured it's basically like wearing a bikini. I hope it's not bothering you."

"No, not at all."

"That's good to hear."

He stares at your panties as if trying to see through them. You complete your transaction and turn around to go to the car. You intentionally wiggle your butt so he has a nice view on the way back.

This is going great so far! Now you have a more serious choice to make. So you play it safe and remove the shirt or risk removing your panties now?
