No it's not hard, but I still very rarely see people supplying their own bags. Instead they're paying five to ten cents per bag which used to be free but now is a vector for profits to the company, and which used to be made of thin flimsy plastic but is now thick plastic that will take much much longer to degrade. Like I said these bans have been great for the grocery stores profits. It's nice that they do quantifiably reduce plastic waste, though.
