Probably gonna turn down this $16/hr job

Just can't get past the fact of getting up at the cracked of dawn, working the busiest shift, and still not taking home enough to have anything leftover from that paycheck. Seriously why the hell bother. I was told it would start at $19 and was the shift i wanted. HR woman was already a nightmare to deal with, calling me asap because she didn't check her email and see my response. Talked to my mom and she agreed to not bother. At $19/hr I would have had money leftover and that schedule would have allowed me to do more... at $16/hr and the lousy shift I'll be there a lot and not have free time for anything else
