American culture teaches us to be suspicious of street vendors and to buy everything at a store (or online). But in Mexico, street sellers are sometimes really great. It took me awhile to figure this out.
Here’s an example. This tape guy outside a market in Cuernavaca, Mexico, has every kind of tape you could want, and probably sells are very good prices. Tape is one of those things you’re not going to make a special trip to the store for. But when you see a tape guy like this on the street, you think: “Oh, yeah. I need some duct tape.”
Street sellers actually appear to be a valuable part of the Mexican economy.
