Almost every single day you have a break for lunch.
If you use the client canteen, it would actually cost you less rather than going out in terms of money.
But you move less, and spend less time outside. The canteen needs more money from your client to add seats for consultants, then the client has to reduce consulting cost as canteen maintenance gets more expensive.
If you go out, you help the city bar to get more money, then improving, then attracting more people, who will be more pleased of spending more time there rather than in the office. Client employees are attracted as well. Working less.
Needing more consultants.
That’s all folks.
