I allowed WIFI access to my maid, she has a smart phone and ipad. She promised me that she will not use her smart phone or ipad during day time. She has been with us for four years. Now, she uses her ipad and smart phone all day long, even when she is doing chores in kitchen, downloading movies, songs, watching movie etc etc. See! I regretted but it is too late. If I cut her wifi, our relationship will definetely go sours. Thus, look before you leap!
