Hi - Just my thoughts on arrogant merchants. For many people their products and stores are labors of love, their babies, that they spent hours on to make perfect in their eyes. then someone comes along and criticizes it - and whether the criticism/suggestion is justified or not it is possibly upsetting to them. You have the option of not purchasing their product if you don't like it the way it is. But I know when someone approaches me about something I made, depending on their approach/suggestion my first instinct can be defensive. Not to the them of course, but in my head. And then i have to remind myself to see if their suggestion is valid and useful. but I keep this in mind when I see something I like but there is an issue about it that might keep me from buying it. I tend to just move on and look for a product that better suits my needs rather than possibly asking for or suggesting changes that may not be welcome.
And, customers are also sometimes extremely arrogant and demanding. I have had some that have been downright nasty for things that had nothing to do with me. So it does go both ways.
