Personally, I could care less what someone's ring tone is. What bugs me is people who won't or don't turn it down, esp at work. My one boss is guilty of this. for the longest time it was a song, one which I could not stand. Now its simply a loud phone ringing, and her text message alert is annoying as well. My issue with her is that she is a special snowflake who will not put her phone on vibrate. ever. so we all have to listen to it all day long...she's been spoken to about it but it falls on deaf ears.
If I'm out at the mall, or somewhere ese in public, as long as I'm not at a movie or something like that, as long as its answered, doesn't really bother me. But if I'm at my other job, trying to help a customer, and their hpone keeps going off, I get a tad annoyed. I'm giving you my time and attention, you should extend the same courtesy to me.
I always keep my phone on vibrate at work, but every now and then I forget. For Halloween my ringtone was from Psycho, and i forgot to turn it off, so it rang one day at work. Oops.
