No, it isn't. It doesn't affect the wage they have to pay them. It just affects whether the employees need to pay taxes on tips.
it will absolutely affect the wage they are paid, it will be used as a constant excuse to not pay more than the legal minimum (2.13/hr as long as tips are greater than $7.25/hr)... probably used to justify additional tip stealing that happens pretty much everywhere, people will tip less because of it
servers are treated like absolute garbage
It may not affect the wages they have to pay but may affect wages they pay if they pay above the minimum.
