I was eating at Panchero’s a few days ago and I heard someone ordering a burrito. When the employee asked the customer if he wanted hot sauce on it, the guy said, “Have any super-hot sauce? Something under the counter?”
That would be awesome. If I ran a Mexican restaurant like that, I’d keep some Dave’s Insanity sauce or something like it under the counter. I might pour the sauce into a small, dented, tin canteen, just for the effect.
That’d stir up some word-of-mouth marketing.
