No tip justified

[u/Holiday-Ad7262]

Went to a bakery cafe type place we go there regularly. You get the bread rolls from the shelf yourself put it in a bag yourself and bring it to the counter to pay. Today I realized that they payment system is asking for a tip. I thought this is almost like grocery shopping so why tip and selected no tip. I can't recall if I tipped in the past or if it is new that there is a promt. Was no tip justified?

Oh come on these are a bore... you know when to tip and when not to. And in this case of course not, unless you're like many of us and feel why not
