At some point we all have to decide how much our time and effort is worth. It took a while but I finally figured out going through all of this with so many flakes just isn't worth it. Spending an hour for a round trip and other associated time and actions just isn't worth saving a few bucks or buying something that only costs a few bucks.
Great advice.. Never deliver or pick up alone. At the very least of things to false accusations are easy to make and it's your word against theirs. I worked in a school for decades and it is now a common and sometimes required practice that you are never alone with anyone especially a child. This is for YOUR protection. Always have someone with you or meet in public where cctv might be being used. There are a lot of mentally ill people out there and it only takes 1 to mess up your life for a very long time and there doesn't always have to be a motivation for trouble.. Stuff just happens..
