Burger King springs

Very upset with the mr delivery driver that come to deliver fiid ordered from burger King never in my life did I have to explain to anyone what rent I pay at my shop why am I questioned by there driver demanding to know what rent we pay here and when I said that's private he has a bad attitude and slaps his tongue and caried on. We lift a tip and was not even a thank you as we all know we also pays delivery thing is discusting that I must explain myself to a driver and then have to receive back attitude.
