I was recently at the local CVS, and I saw the following sign on the bathroom door. It seemed very strange to me. Unless you read the fine print, this is very confusing. It certainly looks like CVS is offering to text you when the bathroom is available. What’s next? Those little buzzer devices they have at The Olive Garden? (By the way: don’t do business with them.)
For the record, CVS is actually offering to text you when a sale item is in the store. They still only provide old-fashioned bathroom queuing.
