Hi! I am currently designing a four-session workshop for young adults (18-30). The topic is business english, but in such an elementary level that I will be mainly teaching everyday English applied to business environements, such as answering phone calls, giving directions to customers and so on. One of the strong points that I want to add is the "common mistakes", such as confusing "a little/a few", "degree/career" or not being able to say dates or telephone numbers. I was wondering if you could help me with these common mistakes in elementary level, words that students confuse that have to do with "business" English (situations like dealing with customers in a shop or at a restaurant, answering a few questions in English in a job interview...). Can you come up with any?
