Keep tipping zero. They will openly brag about how little they work.
Servers have this thing when you press them about why they deserve more, they tend to lie about reasons like above about taxes (maybe they arenβt lying and just dumb hence why they are a server). Also makes over 50k a year with part time employment. Just further cements that they are overpaid through tipping.
Iβm not going to support their lazy lifestyle where they mooch off tips from other people.
