But how am I supposed to control my workers if they work from home?

Not in Berlin. The Brand calls themselves Berlin Döner and they operate in other Citys too. I personally got better Döner for the same money(in my region).

A quite big Döner Brand in Germany(Berlin Döner) has shops like this and they aren’t even that bad. They aren’t outstandingly god but also not bad. Its maybe a bit overpriced for 6€(at least in my city it costs 6€).

Yes

I meant web apps

I would go with the web apps for the office stuff and recommend Thunderbird as a client for outlook.
