Yeah, the blinking lights are just blinking lights. Mainly there to look cool

Tooltips are an ongoing project. I worked out how to add them fairly late, so most things don't have them yet.
Changing the subject, I've been thinking on the subject of the girls' level in the game. I'm thinking that low level girls can probably get through a lot more customers in a night, but they get paid less per trick. The high class whores do comparatively few but the amount they charge more than makes up for it.
Something like this, maybe:
lvl 0 10 mins 10 sigils # 1440 max income for 24 hours working flat out
lvl 1 30 mins 50 sigils # 2400
lvl 2 60 mins 150 sigils # 3600
lvl 3 3 hours 750 sigils # 6000
lvl 4 6 hours 2000 sigils # 8000
lvl 5 1 day 10000 sigils # 10000
The Sigil being the currency used in Abby's Crossing.
So your typical level 0 scrubber might have punters lined up round the block, but to work that fast, she's basically dishing out quick handjobs and blowjobs and pushing them out the door and leaving them to zip up in the street. She sees a lot of customers, but no one is going to pay a lot for that sort of treatment.
At level one, she gets half an hour rather than 10 mins. That's time enough to make a little small talk, make the process seem a bit less impersonal to the customer. It also gives her time to wipe the spunk from her lips before she sees the next john. The punters feel better about it and they pay more.
At level two, she's giving quality treatment. You get time for a drink and some chit-chat. She'll do it more than once if if the customer wants, maybe a little light roleplay.
Level three you're hiring more of a call girl than a whore. This is someone who can accompany you for a meal out and talk to you about whatever interests you. She could be hired to dance, maybe do a couple of your friends for a small tip on top.
Level four and you've got a professional escort who can pose as your steady girlfriend, or provide the entertainment for a batchelor party. You're paying good money and she's more than willing to earn it.
Level five, you're hiring her by the day. We're leaving "call girl" and "escort" behind now for "courtesean" This is a girl you can hire to accompany you for a holiday by the sea, or if you can afford it, to live with you as your wife.
Of course, high class girls cost more in maintenance. You're not going to get barons and earls to thousands for dirty waif wearing a greasy shift, no matter how good she is at fucking. They expect silk and perfume and if you want your girls to operate at that level, you need to supply the tools of the trade. And there's also the question of availability - clients who can afford the level five treatment are comparatively rare.
Anyway, a few thoughts on how we might nuance the level time and payment question a little. Comments welcome.
