That's childish behavior and she sounds like a buzzkill. How old is she?

Her:( replies after 3 hrs) ? forget it then, not sure what to eat, maybe I’ll stay on a diet Her: I might just get a facial massage (dermatologist) instead

She took your joke too seriously and took it as a rejection.

What is this little tantrum ? It’s like she didn’t get my sarcasm and got mad, and now threatening to decline my meet up.

Right. Shit happens. Women are moody. She's taking a stupid step back, so now you have to take a step back (for a time) to avoid being a loser.

I find it funny as if a child a throwing a little tantrum. I was thinking was ignore her tantrum

right

and invite her to another restaurant. Is this the right decision ?

No. She's being dumb and now you're rewarding good behaviour / chasing / accepting her disrespect.

How about "Ok, sounds like you're super busy with your facial".

Does this count as shit test ? Or should I just ignore her until she clams down?

Doesn't matter what the fuck it is...... it's not good enough so you need to hand out a gentle punishment. Increase delays, accept the none-meeting, act distant. This should trigger more interest from her (if she still likes you) or disinterest from her (if she doesn't) - both are good.

This is why I rarely try to be sarcastic or make any risky jokes over text, it can easily be misinterpreted. Though in this case this girl is just being childish

Keep texting for logistics only and tease her in person

Just text her "remind me to give you extra spanks" and stop taking plates on dinner.

Any threats or ultimatums given to me, I immediately next, downgrade, or ignore. She better have a good reason and apologize. You chasing her or apologizing for doing nothing wrong just puts you in a weak position. She will see you as easily to manipulate, and we all know girls don't respect men they can easily manipulate.

Don't deal with BS. Stop trying to placate to this woman.

If this was a child I'd tell him to shut the fuck up or he will be handled. That's how my dad did it to me. Never threw a tantrum again. But this is a girl, so just ignore, or send a yawning emoji if you must.

She's shit testing you to see if you'll apologise and try and make her feel better by escalating over what you would normally do. Do not reply use those other spinning plates and wait for her to come back to you, once she realises you won't fall for it she'll come back if she really wants to, if she doesn't no great loss

YOU MISSED THE CUE! The only acceptable answer to that is;

"I'll be right over to give you your 'facial'"
