Group Chat Ethics?

I'm sure you know how infuriating it can get when we're in a group chat trying to get a message across?

What I'm saying is best depicted in...
the following scenario:
A: Hi guys. I'm gonna hold a BBQ this weekend, specifically on Saturday at 5 pm. Looking forward to seeing you all then. If you can make it, please reply by tomorrow. Thanks.

B: I'm not gonna be around, sorry.😔

C: I'll be there.😀

B: Say! Why not have the BBQ the following week?😯

C: I can't make it the following week. Why can't you be there this week B?😟

B: That new mall in town is having a grand opening sale. I can't miss it.😉

C: Really? What are they highlighting?😯

B: Yeah! Everything that you need to match your new nightie!😍

C: Really? I've had to dispose all my nighties coz hubby's getting bored of them😕. Do you think they'll have the latest nightie collection during the grand opening launch?

B: I'm sure they would. But you better check them out this weekend.

D: Hi y'all! How's things? What's been happenin'?

E: There's a nightie sale this weekend. 😐

D: Yeah? Anybody goin'?

C: I'm meeting B for the sale. Anybody wanna join?

F: Guys! Did you see what happened behind the canteen yesterday?

G: What happened?

D: B and C are gonna meet for nighties!

G: What?

A: Hey guys! What about the BBQ?

G: BBQ? Who's making BBQ?

A: I am.

C: When is it?

A: This weekend, 5 pm!😠

D: Why weren't we invited?

F: You won't believe what happened behind the canteen.

E: Say, didn't that canteen previously sold barbecued lamb?

D: Nah! People wanted chicken chop. So they came up with a new menu.

C: I like BBQ lamb better.

B: Yeah! We should organize a BBQ party soon. Anybody interested?

A: 😡?!#^
