Do I dare? Piss in front of the whole column!

That would be exciting - a piss in front of a whole column of lorries. When I wanted to go to the toilet at the service area, I saw all the lorry drivers and the idea came to me spontaneously. They're all sitting in their cabs watching me, which is pretty nerve-wracking! But I don't know if I should risk it. How will they react when they notice me, I feel a bit uneasy. What do you think, do I dare? Will you help me?
