What extent are you willing to leave your bike unattended (but locked)?

Hi everyone, I just got a road bike and I want to use it to cycle to dinner (get some exercise in). However even cycling to hawker centres will require me to lock my bike somewhere (visible or not) to queue up to get food and eat before cycling home.

I am wondering about the general community, what is your tolerance to leaving your bike unattended (locked or not, visible or not, for how long, what kind of bike?)

Happy to hear and get feedback 😊 thanks!
