Now the thing to do, instead of bitching about it here is if someone has only one or two items, to let the person go in front of you. That is what I do
One quick item is not really the issue regardless of age. The issue is when the person attempts to use age as a “free pass” (without any infirmity or need of special assistance) to simply claim an excuse to circumvent people in the identical situation. (think DMV wait times which annoy everyone equally. Think of a movie ticket line with a person walking to the front and claiming to have “not seen the line.” Think if it was a person cutting to the front of the line of the new X phone because the line is too long and they have to do other errands...)
