[post_page_title]Try before you buy[/post_page_title]
There are many stores that offer ways to try things before you buy them. After all, makeup counters usually have testers to make sure you get the right shade while many stationery stores have paper to try pens.
However, if there’s no trial area, then the chances are you’re not supposed to give them a go. Sadly, that didn’t stop people from trying out different spray paints until they found the perfect shade. Apparently, they didn’t realize the floor is out of bounds for paint trials.
