Rebekah - Desperate Street Meet

After rushing around all morning I'm now desperately late for my meeting and you guessed it... desperate to pee. To make matters worse the sun is beating down and it's hot. My predicament is further compounded because the other party is also no where to be seen? I'm faced with a dilemma, should I chance it and pee by the bench? What if they pull up whilst I am mid-pee, that would be so embarrassing, wouldn't it?
