Quoted from Xanathar:You see the city listed and are not sure which city it is in ( you have never heard of it, and don't have the means to look it up right now. I had my phone but couldn't check as I was busy with something but was able to use it to send quick email)
My opinion, you are rude to ask for it. It takes the same amount of time to compose the email as it does to lookup on map website. Doing it yourself is more useful than the seller doing it because he won't know where you are located and won't know the distance you need to go. Distance will factor into your decision whether or not to see in person.
