To pay or NOT to pay

Non paying customers are the bane of any business. I have had a few people hire me to do photos of a house and then dont pay. I even get a text praising how great the photos were and then get totally ghosted where they dont answer my calls, return messages or emails. I put in a ton of work to get them some great photos and even jump through hoops to get them done as soon as I can, but for some reason, these entitled people think that I dont deserve anything for my work. If it were easy, they’d do it without me.
