Nedbank offers clents an UNSECURED WiFi network in the bank

Went to Nedbank Killarney this morning. While waiting to be called to a teller, I wanted to do some backing on my Nedbank mobile app, which Nedbank strongly encourages. Connected to the Nedbank WiFi and noticed that it is an 'UNSECURED" network! I ask one of the employees standing around and was told that the SECURED network is only for the staff of the bank! There is NO way that I would use an UNSECURED network, especiallyy not for banking! Just warning other Nedbank clients to be alert and NOT to use the inhouse Nedbank UNSECURED WiFi Network!
