How do people typically feel about entering lines in service situations?

Choosing a line feels fairer to individuals because it allows them to have a sense of control over their experience. In service situations, customers often appreciate the ability to select a line based on their perception of wait times and personal preferences. This option reflects a psychological aspect of customer behavior known as "perceived equity," where people evaluate their wait based on their choice rather than being assigned to a line. When customers can choose, it creates a perception that they are in charge of their time and experience, leading to greater satisfaction even if the wait time is similar to that of other lines.

The other options suggest preferences or emotions that do not align with common customer behavior in queuing scenarios. For instance, being assigned a line diminishes the sense of agency, while indifference about which line to enter contradicts the typical customer desire for perceived fairness and control. Wanting all lines to be the same length indicates an unrealistic expectation that overlooks practical variations in customer flow and service speed, which are common in service environments.
