Had a roommate once who was absolute hell. Smoked pot, like all the time. To the point where my clothes in my closet reeked of smoke. Always ate all of my food and never contributed to any of the grocery bill. If he was hungry, he would go to taco bell and buy 2 tacos, bring them home and eat. Then complain because we were out of soda or whatever. Spent 99% of his time on the computer hogging up all the bandwidth playing video games. Could barely keep a job, and would complain that if he paid his rent he would be broke all week. No shit! If I pay your bills I am broke too. It took having the internet and cable and utilities turned off multiple times for him to “get it”.
