Chris/Alex was deliberately taking a risk when he____ in chapter 5 or 6

In Bullhead City Chris works at McDonald’s (ironic because he hates corporate America). During this time McCandless tries to hide from his coworkers the fact that he was homeless, camping outside of town and living in a semi-deserted mobile home shown to him by Charlie, who McCandless meets in a restroom, and finds to be rather crazy. This was rather dangerous to do.
