That's not what I'm saying. I'm saying there is no reason for a person not to (unless he is seriously concerned about the guy's job) since it doesn't require anything extra from you.
I ask again then, you only throw out your tray because it's convenient? If the trash cans were not in your path to the exit you wouldn't do it? Now who's lazy? Oh and menus and silverware are on the way in to the restaurant, not out of the way. The other things, maybe.
No, I don't not do it to save someones job. Just because I leave something behind for someone else to pick up (whose job it is to do so) doesn't make me lazy. If i didn't throw my trash out at a McDonald's then yah, you can call me lazy.
And if it's not laziness, and you're not genuinely concerned with the guy's job, then what is it. Sounds to me like you're saying you don't do it because you know someone else will. That sounds a little lazy to me.
