Not in a while, but yes.
< has also never had a tofu burger, but has had a number of tofu dog sammichz, a tofu salad sammich, a tofu quesadilla, numerous boca/veggie/garden burgers, and copious amounts of money before.
If a lovely tofu dog sammich was left on your counter with "I HAVE YOUR CAT; EAT THIS IF YOU EVER WANT TO SEE IT AGAIN" written in mayonaise, dijon mustard, and pickle relish on the wall, what would you do?
