In general,
it has been found that routine shopping by consumers is task-oriented and they try to complete their shopping in a pre-decided time.
Impulse purchase tendency is high when task-oriented consumers are in queue for making payment in a retail store; since checkout hardly provides hedonic benefits, consumers simply want to get it done quickly (Zeithaml and Bitner, 2003).
Some researchers showed that lack of time may lead to failures in purchase, which is not in conformity with previous research (Park et al., 1989).
