I don't doubt that, you're probably from somewhere around Ostrava. There are of course regional differences. I'm from Brno and instead of "jít do práce" we usually used "jít do hokny", "jít do háčku", or just "jít makat". Whenever I hear word "robota", I connect it with my grand-grand-...-father who was forced to work ("robota") by "dráb" (overseer) and didn't like it. So he cut overseer's head with his scythe, became a village hero and founded a church there.

So I'm hard-wired to dislike "robota".
