What would you do?
Please do not go with a stranger. When you are traveling people can see you are a tourist. They can lie and take you anywhere and do anything to you - you do not know what might happen. In general people do not do things "for free"... ask yourself "why would this person want to help me?" -------- Protect yourself while traveling, say no thank you and/or walk away. If you need information or direction while traveling find an official person or police officer at / near / working at the location.
My sister's friend got robbed and killed trusting a "nice" person who wanted to "help" her overseas (not naming the country). Please don't be a victim.
Yes, there are nice people out there - but there are just as many bad people. Travel smart. Please.
