Taxis can be a pain too

.......It's fine to be dismissive of vendors. Being dismissive of vendors is not necessarily being rude. Personally I find it rude that folks disturb me to try to sell me something when I am obviously not looking to buy anything.

I realize business is slow, especially for taxis, with 'way too many permits issued, but....

A foreigner can't walk along the street, or stand waiting for a bus, without every taxi that passes - in either direction - honking its horn, flashing its lights, calling "Taxi?" out the window, or all three. What's with these guys? Don't they realize that if we wanted a taxi, we would somehow indicate that fact by waving, or calling, etc?
One night in Mazatlan four of us were standing on a sidewalk having a conversation. A pulmonia pulled up to the curb and honked his horn at least a dozen times, not satisfied until he had forced one of us to interrupt our conversation, turn around and inform him that, no, we didn't want a taxi.
