*This question seems like an opinion based question, but here is my opinion on the matter:
Yes the cell phone is changing our views of what is polite and impolite. It is indeed impolite to talk on your phone while you are ordering a drink at Starbucks, because then you aren't focusing on ordering instead you are focused on your phone call which can interfere with your ordering.
Hope this helps!
This is my opinion: I don't think it's very polite to order a drink while talking on your phone. But if you really have to, you should have your order written on a piece of paper or something. It's just rude to talk to someone while distracted that's all.
