I have a question. I was wondering if this shop can do joints for free, for an example if I buy weed and if I ask them if they can roll them into joints can they do it?

We have prerolls for sale or could sell you a roller to use yourself they are really very easy to use !!

Because I went to another shop long time ago in Pico Rivera and I asked if they can do it and they did it so I was wondering if this shop can do it or I have to pay them

I don't think anyone would do it for free. I use "Raw" cones. Pretty easy !
