Its one thing of someone has a personal minhag that doesnt affect anyone else Its quite another if your minhag or chumra does affect others especially if it might have negative consequences on others.
I will repeat the following story. There was a woman on line at the grocery store for pesach and she had a bunch of items. She clearly wasnt well off. One of the items was bounty paper towels (or similar non jewish brand, I forgot) SHe then remembered that the Blumenkrantz book said not to use these towels because the glue on the cardboard roll was kitniyot. She then proceeded to return the bounty paper towels and get a Kasher L-Pesach paper towels and because it was more money had to put back some food all to keep a chumra.
