ok so at work today, there was a new guy who didn't know how to work the cash register. so every time a customer would come through, he would say "I'm sorry I don't know anything; I'm new." It was almost as if he was giving an excuse for not knowing anything. what is a synonym for someone who gives excuses for themselves? it's only one word and we think it starts with the letter P. It is a very sophisticated word. PLEASE HELP!!!
