McDonald’s Drive Thru By Gnz on December 6, 2012 in Americanisationisms This is probably fine in the US, as the English language there has accepted that thru is a word. Here in the UK though? Nah. We have got some proper words, and we are going to write them out in full. Since McDonald’s is an international company and brand, the original sign is all about making the experience regular for all customers, no matter where in the world they are.
