This happened to me twice last night while ubering...Uber request, you drive to the pin,nobody anywhere, you text the passenger "Ive arrived" they call or text you "im at so and so" you dont know where the hell that is..you text/call back "im at the PIN" they dont know where the hell you are....so what do you do? Do you play the go find them game, do you tell them to go to the PIN, or do you just cancell right away??
