It's even done regularly in some cases, various US airlines take "offline" card transactions and process them later for food & drinks.
There are of course limits on how big an offline transaction you can take intentionally or unintentionally and probably the airline wears the full cost of failed transactions in this case.
Doesn't matter that much when its for a $5 coffee, plus they know who you were if they really wanted to chase it down.
And as mentioned electronic terminals absolutely have automatic offline modes also.
