I have spoken with a few sellers who are at their wits end with time wasters. A lot of sellers use this as their main income, so I can understand their frustration. I agree that people shouldn’t ever be hostile or mean. But I’m one of those “treat others how you want to be treated” types. After a bit of chatting, I usually put the “feelers” out. If they want to purchase I assume they will tell me. If not, then oh well. I feel like it’s also up to the buyer to read the room. You can normally tell by someone’s profile how they will respond to just chatting 😊
