mate i would have smacked the guy. I have been to do quotes where people say the other guy did this and did that and sometimes have even said to them have you spoken to him about it there may have been a good reason if it was a once off. I will put in a quote if someone asks and if its less than the other guy and they chse me thats fair but i would never deliberatly try and steal someone elses work. If you get clients by stealing there work the next guy thats cheaper will just steal them off you. I belive we all want a good run with regulars not loosing them cause someone else is cheaper.
