<human>: I work in customer service. People come up to the counter and order food and drinks from me. Just yesterday someone proceeded to make a phone call (not receive, make) while she was next in line, shout into the phone, and whisper to me. She was visibly irritated that I had to ask her to repeat herself several times. This happens almost daily. 

By making the decision to be on the phone while buying coffee, lunch, gas, smokes, groceries, whatever- you are being disrespectful of the human in front of you. 

It is particularly obnoxious when someone with a phone glued to his or her ear resorts to:

-Playing Charades 

-Whispering

-Mouthing Words (lip reading is a necessary skill in customer service these days)

-Shushing the person behind the counter
-Giving a "One Minute" finger when the person behind the counter addresses them or responds to their order

-Pointing at the phone smiling and shaking their head to excuse the rudeness (it doesn't). 

I understand that sometimes you get a call at a bad time. Next time consider ignoring it for a moment. If that is not an option, simply ask the person on the line to hold while you order and pay. Take the phone away from your ear for the entire transaction.  Be a good customer.

Give me the gist of the text in a nutshell
<bot>: Having a phone to your ear while ordering something is always rude. Take the phone all the way from your ear. Return to your phone call AFTER paying.
