Standard Rates at Sub-AMPS

I just started visiting some of the local Sub-amps in the Plano area. What do you guys think the standard tip is at a Sub-Amp in the Plano/Frisco/Allen area for all three levels? I assume the house fee is 40 hhr and 60 hr.

L1 = ??
L2 = ??
L3 = ??

I wouldn’t know, but a friend told me the following:
- L1 $40
- L2 $100 (includes DATY)
- L3 $150 (includes everything above)

A lot of variables here.. younger gets more $ than older.. the fat ones tend to want less.. the above is just guidance. Good luck!
