Even if you aren’t going out to eat at restaurants right now, you are probably ordering takeout and/or going through the occasional drive-thru and, when you do that, you almost certainly come into contact with at least one person—the one whose job it is to physically hand you your food. That person would appreciate if you wore a mask (as would I).
Whether you are answering the door for a delivery person or picking up food from a window while standing on the street or sitting in your car, you are going to be within six feet (aka “spitting distance”) of a service industry worker, and that worker deserves both the physical safety and peace of mind that comes with each of their costumers wearing a mask. If you’re a crazy science denier who doesn’t believe masks are effective, you should wear one anyway. (There’s no reason to be a crazy science denier as well as someone who makes a restaurant worker’s life more stressful or annoying.) (Also, you’re wrong.)
Even if you choose “contactless delivery,” you should wear a mask when you go to the door to collect your food. I cannot tell you how many times I have opened the door to see the delivery person still standing there, or still within six feet of the doorway. Wearing a mask is not only the safest course of action, it shows that you care about—or at least respect—the people who are being paid not nearly enough to bring and/or hand you your food in the midst of this pandemic. Plus, it’s an easy thing you can do to show someone else you are at least a somewhat decent human. Well, that and tipping very well. I do hope you’re still tipping well.
