It really does depend on the context/situation.
If someone has done you a favour and you tell them that you don't know how to thank them, they could say: "You can thank me later" in the sense of that you can do them a favour later and help them with something.
If someone does you a favour and you don't thank them for it and don't seem grateful, they may say in a joking or sarcastic way: "You can thank me later" as a gentle or subtle (even unsubtle) reminder that you should be grateful to them.
If someone gives you a word of warning or tips to avoid you getting into a crisis and you think the advice is unnecessary, they might say: "You can thank me later" or "you'll thank me later" in the sense that although you don't take their words/actions seriously now you'll eventually realise that they were right and will be grateful to them - even if you're not grateful now.
It is one of the informal ways of saying goodbye to someone. Apparently, this phrase has been derived from a 50's pop song. The person to whom this phrase is being said, says- 'In a while crocodile!'
Mark: See you later alligator!
Janet: In a while crocodile!

In England, "28 days later" is roughly the equivalent of "four to six weeks later" in America -- like when you order something out of a catalog and they say the merchandise will be arriving in the near future.
Thank you for ordering "The Greatest Hits of Kathie Lee Gifford." You can expect it 28 days later.

Used to describe Jeff Bezos the day (July 20, 2021) he took his first commercial flight into space too late. King of Amazon may have had eyes on the wings and astronaut title but he didn't meet the requirements in time. The Federal Aviation Administration chose that same day to update the requirements to join the ranks of astronaut. It was the first major change to the rules since 2004. Turns out Jeff didn't get his wings or title due to not meeting one requirement. He only got a $5.5 billion honorary title and only 4 minutes in space. Gee, that was fast. Just one day before and he would have qualified. Well played FAA. Savage af.
Jeff Bezos spent $5.5 billion for an honorary title and 4 mins in space because he is a delayed space-u-later. Jeff is definitely big mad and probably butt hurt at the FAA for screwing him hard.

Being a premature space-u-later caused Jeff Bezos his space wings and the right to call himself a astronaut.
This is an old use and still use for this catch phrase to tell someone see you. and the answer for it after while, crocodile, alligator and crocodile were brought for the sake of rhyme.
OK, see you later, alligator.
After while, crocodile.
