I always use my phone to "vibe" with guests. I like to save money, as well as help others to. I have unlimited data, but target has free WiFi in case I didn't. Recently, I was caught doing it with guests on the floor. Because of that, I was able to pick out a toy for one of my kids for christmas.
I don't look down on anyone who doesn't do the same, but for me, I'm happy to do it. It's a big reason why guests keep coming back to target, the staff goes out of their way.
