Why do people understand that they are supposed to tip waiters but do not understand that pizza delivery guys use their own cars and gas and bring them a hot meal to their door and either give them nothing or maybe a dollar or two. My husband and I both lost our jobs and this is all we have at the moment and the more expensive the nerighborhood the less the tips. Do they not understand that he makes minimum wage and is expected to live on his tips? I watch people give a dollar for a girl at Sonic to bring them a hamburger or a coke 15 feet to their car . We delivered flowers last Valentines Day for extra money and out of 26 deliveries we got one tip. of $2. Please help people understand that this is a job !!!!!!!!!!!!!!!!!!!!!
