Thinking the worker I had an interview with (that ended with 'I'll think about it ') has probably said that she can do all the hours privately. Maybe not.
I'll think about it to making your shifts permanent and pay you $10 more per hour and increase your hours, with the real possibility of getting close to full time permanent hours, which I'd be obliged to offer as perm part time after 6 months.
Cunts always overestimate their value.
