It has been demonstrated that time pressure negatively affects perceived service quality and induces anxiety that tends to prompt shoppers to overlook shopping list.
The arguments can be furthered that overlooking shopping list induces impulse purchase tendency.
Researchers have established that time pressure affects shopping situations like unplanned purchase, brand switching and impulse purchase (Park et al., 1989). Research on retail consumer behavior also demonstrated that consumers under time pressure often choose products they normally would not choose, and act impulsively (Dholakia, 2000; and Chaturvedi, 2013).
