Hints from Heloise have been given out to readers who struggle with reading small print instructions on product labels. Senior citizens are advised to wear black or white print on their product labels, which are difficult for them to read. Older people often leave shopping carts in the middle of the aisle, making it harder for others to pass them. Older readers also suggest that grocery store managers and shelf-stocking employees should not leave carts in their own store. The author suggests that writing a thank-you note for the recipient indicates appreciation and willingness to make it easier for younger people to express their appreciation.
