“Check if you haven’t” or “check if you have” left any thing behind?
What might be trivial but it didn’t sound right to me when I thought about it, so I decided to ask.
I’ve heard an automated message saying “please check if you haven’t left anything behind” Is it proper to say “Please check if you have left anything behind” and not “to leave anything behind”?
What is it like to become a university or a professional body?
