1. Texting/Talking at the checkout lane
Don't really care if they're waiting in the queue, but if it's their turn and they're still on the phone, we're going to have a problem. Will probably ask the cashier to skip them and serve the next guy.
2. Texting while walking & not paying attention
Don't really care, it's their stupidity. If they happen to also fall into a fountain, hello youtube video.
3. Noisy game / movie
Depends really what the situation is, this is only a problem if we're stuck waiting for something and not able to get away. Movie, awesome, time to discuss plot twists and spoilers with buddies. Game = backseat driver
4. Talking on the toilet
Holy shet, someone doing this is basically setting themselves up for trolling. Haven't forgotten those 101 juvenile toilet pranks in high school.
5. Paying more attention to phone than conversation
This is easy, just walk away and talk to someone else.
6. Photo tagging
This can easily cause a lot of damage. Depending on how much, the offender will either be looking at bruises or a new phone. Come on - how hard is it to not be a compulsive photo tagging dick. Advance warning given, fair game.
7. Antisocial phone usage
Don't really care, but not gonna repeat anything you missed.
8. Talking about personal issues in public
Another wide open setup for trolling.
9. Shushing people while on phone
This will only spur us to talk louder. Seriously. You'll probably even learn something, we have topics specifically for these situations. Like in-depth discussions of physical abnormalities and diseases.
10. Texting someone instead of walking up to them and talking
Huh? Weird maybe but this one isn't a problem.
The guys I hang out with really appreciate it when someone gets a call and excuses themselves to walk over a little ways away to take it in (semi-) privacy... or actually looks at who the caller is, and shuts the phone off to return the call later. Because, you know, not every call is a freaking 911 help mom is on fire pick up the phone now.
Ditto texting. How hard is it to say, "guys, gimme a minute, I gotta reply to this"? Or actually wait until you are (1) not in a checkout line, (2) not walking in public where other people might run into your not-paying-attention ass, before replying.
Common sense isn't common enough.
