Compared to lunch costs, commuting costs, time saved commuting?
I don't understand the question.
I speak English just fine, but I don't get what you're really asking either. Why would someone get additional benefits for WFH? It doesn't make sense to me. Is it that there are benefits that can only be used on site, and as a result the business is compensating for the loss of access to them?
The bosses wife has offered me friends with benefits if that's what you mean OP?
