Because nothing could make me want a cheap, mass-produced junk sandwich made by an underpaid high school dropout who thinks that COVID is a hoax than seeing a basketball player, comedian or some other somewhat-famous tv personality hold up an obviously rubber facsimile of a grinder* and tell me how much he enjoys eating at Subway when he isn't doing the basketball or comedy thing.
*I'm from New England. It's called a grinder or a hoagie. It can only be a "sub" if it's cold, and Subway Sandwiches can be hot. So they are grinders or heroes, not subs. I feel like I should block comments now, just in case this one of those triggering subjects that I'll wish I had avoided, like "Howard Stern is overrated" or "DirectTV ads are racist."
