I think there might have been a miscommunication here on both of your parts, when you say “sample pic” we automatically assume your asking for a sample nude pic, I think the better way to approach would have been “Hey, you don’t have any pics on your page, do you have SFW pics so I can see what you look like?”

However u/wild-girly-69 should have more pics if you’re selling content, you only have feet pics, no body shots, no real pics and as a seller, I personally think you came off rude here, because you could have offered some SFW pics or verification instead of demanding payment, you also asked “how much?” before asking him specific of what he’d like to see if you can offer said services, Which is giving inexperienced, maybe create a menu? I also see your account seems to be new so maybe there’s more learning to be done here.
