Study: Long lines mean less customers

DALLAS A survey of 13,000 shoppers by M/A/R/C Research found that 10% of shoppers will leave a checkout line if the wait is longer than four minutes. In addition, 43% of those surveyed said long lines affect their decision to shop a particular retailer in the future, and 3% said they would stop visiting the store all together.

"Retailers really have to focus on keeping their wait times under 4 minutes with the negative impact of even one minute more," said Tony Amador, senior vp at M/A/R/C Research.
