I find the ceremony around wine service to be cringe.

has anyone ever sent it back after the tasting

I generally think the server will immediately know if the wine is corked as the smell is unmistakeable. 

If you send it back because it's "corked" you likely have no idea what you're talking about and are a jerk (sorry)

i also asked a server this recently lol (she said yes, but that they have rules around price of bottle. like if you taste a $200 bottle and send back, you still need to buy a roughly equally priced bottle)

yeah if it's corked.
my sister is such a g, she just sends it back if she doesn't like it 🙈
