Hi i am student in S.Korea. nice to meet you~!!<br/><br/>Now, I am reading a grammer book, and I find the expression, "As long as you pick up the tab" , meaning "as long as you pay the bill".<br/><br/>However, after I read this expression, I can't find same expression in Google.<br/><br/>But, there a many expression "Pick up the tab", Is this an idiom?? there isn't this idiom in dictionary..<br/><br/>I wonder whether "As long as you pick up the tab" is natural or strange.<br/><br/>And Though this expression isn't used in usual, Formally is it possible to use?<br/><br/>I 'm so confused........<br/><br/>Thank you for reading, Good Luck
