The Canvas Gallery and Cafe shuts down weekend WiFi

The Canvas Gallery and Cafe, located in San Francisco’s Inner Sunset district, no longer offers its patrons free wireless Internet access on Saturday and Sunday. There are now signs throughout the space to inform patrons of free wireless Internet Monday-Friday “with purchase.” This change in policy happened within the last week, as I was at the café and online last Sunday. I assume the change allows for greater turnover during weekend hours. I know of other businesses who choose not to offer wireless access because of this same turnover concern. Is wireless Internet access another perk reserved for off-peak hours? [Update 7/19: Wireless access is now 7 days a week. New signs were added to ask patrons to please spend no more than ninety minutes at a table on Saturday or Sunday.]
