Apparently, there are multiple reports of Microsoft employees advertising their products at Wii U events taking place in select Best Buy stores this week. One report says a Microsoft employee tried to convince people who were waiting in line to demo a Wii U game to pre-order the Xbox One. According to another report, someone wearing a t-shirt emblazoned with the Microsoft logo lingered around the Wii U event and talked to people around a demo station. The next Wii U event at Best Buy this week takes place on Saturday, June 15th.
