Silly questions

If you work for Coke, can you drink Pepsi?

If you work for Proton, can you drive a Toyota?

If you work for KFC, can you enjoy McDonalds?

If you work for HP, can you use a Dell?

I'm not sure whether the staff of these companies are allowed to consume/use a competitors' products. Chances are these people won't, not because of restriction by company rules but because normally, they would be entitled for free products or hefty staff discounts.

Companies like Colgate, Unilever, etc. have lots of freebies for their staff. I know BAT gives monthly cigarette rations to its staff. I work for a property developer and if the same rules applies, where is my free house!!???
