[SBLOCK=OOC greenstar]Hrm. Probably gone the other way. The best way to decide costs/fees is estimate how much it costs today (bar room tarot reading? I wouldn't pay more than, ooh, $10) then divide by 15 ($10 / 15 = 60 cents (ish)) and because things were generally cheaper then than they are now, knock about 20% off the price. (20% of 60 cents is 12 cents 60-12=48). So I'd say round it up to 50 cents per reading.
She probably does readings two evenings a week after lectures (you think?). Starts at 6, finishes at closing time, 11:00. That's five hours, she probably gets two or three readings in per hour, so she'll be making about $8 per evening, $16 extra overall per week. $64 extra overall per month, $768 extra overall per year. Allowing for slow nights and the fact she might not make every evening, let's round that down to $750. That's a sizeable sum for a student, on top of her grant and monies earned from weekend jobs, selling art and 'gifts from home' which all contribute to her current income as listed on your character sheet.[/SBLOCK]
