World Athletics has banned transgender female athletes from competing in the female category at international events

I've mainly been tipping 15% and recently read a few servers say that the industry standard is now 20% and that 15% is antiquated.

I understand that cost of living has gone up but that includes food prices at the restaurants which results in a larger bill and 15% tip.

So not only are the restaurants charging us more for the food but the servers are now asking for a bigger tip on top of the more expensive meal? Please make this make sense.
