On my last road trip we took a break in a beautiful forest parking lot. When I asked how long it would take us to reach our destination, he simply said "an hour more". As a precaution, I just wanted to go and pee. My driver didn't mind and even looked at me with a smile. I almost got caught by a few cyclists, but I was able to quickly get out of the situation. Hopefully they didn't notice anything. Well, I didn't have to do much, but at least a little and with an empty bladder we could drive towards our destination in a relaxed manner :)
