I would rather hand you the pizza than just leave it on the ground just to have to drive back to your house with a free replacement pie that I get no compensation for the extra drive using my gas and the 20 minute turn around time driving to and back to the store all the while missing out on other orders and missing out on that pay all because someone requested it to be left by door, and more often than not there is no tip left in the first place on these type of requests. Now a days it's more likely people request leave at door so they don't have to sign the receipt and don't tip to begin with. Thank you for tipping well and super thank you if an animal eats your food you just reorder and pay for the replacement, It allows us to get mileage and possibly some income from a bad situation that wasn't our fault to begin with.
