I ' ve seen systems where a cart expires . Usually with a 5 or ten minute counter . This allows people a little time without holding out inventory . This way the store would also make more money . Since I was going to purchase additional items but now I ' m not purchasing any since I can ' t get the main item I wanted . The extra were just throw ins since I was going to place an order <| sep |> Incineroar , LycanrocMidday and Golisopod . They are all beast in battle <| sep |> 15 % minimum is my rule . It goes up to 20 % if the waiter appears to batheshower . Food service sucks and most people don ' t tip <| sep |> But California is missing like 11 electoral votes that it would have if it was based purely on population rather than each state getting 2 free votes for senators .
