I think your first reply may have occurred because of Bon_Croix’s use of the term underemployment. Sometimes, it’s not good to take the first job that comes along. Although, he did say he would consider working for a chicken place, so I don’t understand your reaction, which I found to be a strong one.
By saying “no” to certain jobs, you can say “yes” to others. I do not believe in taking plan B, because before you know it, you’ve spent two years working as a food servant, you find you don’t have the right confidence and creative energy to apply for the right jobs, and you wind up being stuck. Sometimes it’s better to borrow money while you pursue the correct choice.
I’m self-employed and people will still try to get me to work on Sunday. They’ve only succeeded if they are coming from way out of town, and that was many years ago. I end up doing some preparation on Sundays anyhow, and people still phone you on Sundays. I doubt you can completely improve the situation.
