I've always found line-up discourse to be interesting. The person who is at the till now (or the teller or the counter, whatever) presumably waited their turn in the line-up and now it's their turn to be served. Why should you, someone who arrived later and is now waiting in line, have much of any say in how they conduct their business? What makes you more important than the person who already waited in line? Their wants/needs are likely different from yours, but you want to dictate that yours are better or more important?

I can understand the frustration when you are in a hurry as we've all been there, but to expect others to cater to your needs/wants always felt off to me.
