it seems tho that if it was an issue before, and was brought to your attention and now again being brought to your attention...that you could make a more forceful effort to be aware of your surroundings. as someone mentioned there are safety issues, as well as customer service ones...and again, if you are out cleaning tables or something, you need to be aware of what is around you.

you tend to post these issues with a tone as if "wtf? why do they say this it's just wrong?" but it's not. and deep inside I think you know it. how many times does someone have to call your name for you to respond? in 2 different workplaces? really? I think your superiors are very patient people. more patient then I would ever be. I get it that there are issues but still..you need to put effort into your position.
