Normalizing 15% again

Started tipping 20% for carry-out to support businesses during the Covid Lockdown period, and kept it at 20% for dine-in for a while afterwards. However, the pandemic has been over for a long while now, and I've returned to the traditional 15%. If I tip more, it will be only for exceptional service. I don't expect a server or business to expect any more than this, because the 20%+ was a nice bonus gesture at the time to get us through a difficult period.
