What do you do if you don't want a second date?

I found this story today and LOVED IT!
This is the perfect topic for either an etiquette expert or a relationship expert to discuss.
Here's the story:

Woman Receives Invoice for Her Meal After She Didn't Text Her Date Back
An Indiana woman posted online about a $40 itemized invoice she got for everything she ate and drank when she didn't text her date back after they had dinner. Amanda Burnett shared the invoice on Twitter, writing: "A guy just mailed me a bill for our dinner a few weeks ago because I didn't text him back." The 23-year-old Burnett, who ended communication because she didn't believe they were compatible, said he also sent her a text that said: "To avoid additional penalty or fines, have the invoice paid, otherwise it will be turned in to a collection agency." Burnett ultimately deleted the tweet and made her social media accounts private after a lot of people sided with the man she'd ghosted. (The Independent)

We discussed this on my radio show and I sided with the guy, saying at the very least she could have sent a "thank you but I don't think we are a good match" text.
And of course the ladies we mortified saying this was a too extreme and the guy should have taken the hint.

These are the kinds of amazing radio topics that will have listeners calling in with their opinions. It isn't to late to pitch this topic if you can share what both people should have done instead of taking this to social media.

Discuss:
What do you say if you know there won't be a second date?
If she knew during the date that it wasn't going to workout should she have paid her portion?
How soon is too soon to reach out after a first date?

If you need help crafting this pitch for your media, contact me! I have a ton of ideas!!!
