Giving up smoking for a job is something I don’t believe in. In my case I only smoke after work and on days off, never before or during work. So my smoking has nothing to do with any job. In the past when I had construction jobs, I always smoked, before, during and after, and outworked most.
I had this one guy I worked for who was always talking shit about smokers, lazy, worthless, no work ethics etc etc. he told me I was the best help he ever had and would give me side jobs he didn’t want to mess with. I smoked all the time and he never knew it. I always smirked when he went to talking..
