Poor service

We arrived at Mcd's went to the drive thru and when we got to the speaker we asked the lady to just give us a min or 2 because we not 100%sure what we want to order, her response to us \we work on time here". I then responded to her that we cannot help that the menu you guys have is placed where it is and she has to give us time and there are no cars behind us any way. She was pesistant. Anyway"
