Declined the invitation to dinner, but asked for a rain check.
Origin of rain-check
- The expression may have originated in the era of open-air markets where the occurrence of significant rain usually required a vendor to pack up their goods and leave. The term may also be based on the issuing of tickets to claim property such as a coat or hat check. Before 1889, US baseball fans were issued a new ticket if rain was heavy enough to cause a game to be postponed. Abner Powell added a detachable stub called a rain check that year. This quickly became a standard practice for all major league teams.
