*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.
