Abstract: A method, computer system, and/or computer program product controls access to a wireless local area network (WLAN) access point in a retail establishment. A predetermined retail activity threshold is established for a retail establishment, where the retail establishment has a patron service area with a WLAN access point, and where a determination has been made that exceeding the predetermined retail activity threshold without increasing patron traffic out of the retail establishment will cause an excessive wait time for occupying the patron service area. In response to determining that the predetermined retail activity threshold is being exceeded, a secondary criterion is examined in order to determine if the mobile device should be disconnected from the WLAN access point, in order to motivate a user of the mobile device to leave the patron service area. If so, then the mobile device is disconnected from the WLAN access point.
