The technical explanations offered are the most likely, but also
remember that if you inserted a lot of coinage you may have exceeded
the limit on legal tender (eg a vendor is not obliged to accept 70 10p
coins in receipt for a 7 pound item).

Except the legal tender rules apply only to settling debts, not to
purchases in vending machines.
