From the point of view of both the company and the employees, it is in fact the optimal choice to be able to provide a cafeteria on your own.
If the company has the ability to manage a cafeteria, but still choose to give employees lunch subsidies, now outside of the high cost of meals, so too much subsidy employees will not feel enough to have, but too much subsidy, the company feels that the cost is too high.
But with the same staff subsidies, the cost of self-built canteen, but more savings. Because of their own bulk purchases will reduce the cost, while building their own canteen environmental health will certainly be more hygienic than eating outside, the management is more stringent, the quality of the meal will be higher than eating out, but also saves the employee's meal time, so that employees can actually feel the benefits of the company.
