I think the grumbling you hear from the crowd is their stomachs. People have to eat.

Yes. That would be a good place to start.

here where i live, a second hand market does not exist. it is not in the peoples culture. on the other hand you can buy a lot of food in bulk without it being prepackaged. but even that does not help because i need to put every item in a bag so it can be measured. for fruits and vegetables i can often put multiple items in one bag, but for sugar or flour that doesn't work, so no matter if i buy prepackaged or bulk, i end up with a new piece of plastic that i have to throw away.

I'm not sure about your bulk store but where I live you can just bring a reusable container or cloth bag or something, weight it and put your goods in that.

yeah, that works in shops where you can talk to the owners. they will actually appreciate not having to use their bags since that saves them money. but in large supermarkets the employees usually don't have the courage to deviate from what they are told to do.

or it's simply not practical because the scale is not close enough and i'd be blocking it for to long. on busy days there is often a waiting line to get stuff weighed. so really this only works if the shop expressly designs for reusable containers.
