My experience.
Clementi west market
Selling noodles
I frequent the stall
And I prefer to use the wooden type of chopsticks
for hygiene purpose. Esp so many covid cases.
So one day he told me off. Don't take his wooden
Chopsticks, it's meant for takeaways.
From then on, it's goodbye.

Seriously I think most sporeans won't take cutlery from stalls they do not patronise but foreigners may not know. For such infrequent incidents, hawkers should just be very forgiving and generous. If hawer told me off for very small things I guarantee won't give them my business ever again.
