the highest shelf

on sunday i wanted to buy some napkins. you would think that would be simple. guess again. not on avenue m. modern chemist was closed so i went to glatt mart. all of their paper goods are kept on a seven foot high shelf above the meat case instead of in the aisle with the paper plates. im not sure why. is it because no one uses napkins so they figure they will keep them on a high shelf ? there were some tall people around who could have helped me reach them but they were all holding raw meat. i know im neurotic, but i like to keep raw meat packages away from my napkins so i figured i would skip the napkins.
today i went to anteli's pharmacy to buy paper goods and was able to buy paper towels and tissues, but alas not napkins. they usually do have napkins so perhaps they ran out.
after anteli's i went to the news stand store that sometimes has paper goods. they always have paper goods on high shelves due to limited space. i asked the clerk to get me some napkins and they were so high up that when he reached for them the whole shelf fell down. i felt so bad. all i wanted was napkins.
once i was on a quest for dish washing liquid after a late workday. it was in the days before 7-11 was on avenue m. i found a store that had it, but again it was on the highest shelf. .after that anytime i went into that store the dish washing liquid was on a lower shelf because the clerk was an older man and he didn't want to have to climb .
why is it that so  many staples are kept on the highest shelves? is it just me? does anyone else who goes to mom and pop stores on avenue m use napkins or dish washing liquid?
