Can you bring technical equipment (laptop, etc.) in for repairs today?
No, they are usually always closed on Thursdays. Try it on Monday at 4 p.m. Everyone is open.
Today you can bring anything
Even in Corona time? I'm not sure about that.
Even with Corona time?
Yes you just need to put on a mouth guard
OK. This is not a problem.
Depends on the store.
Corona is a factor, as is the time and the opening times in general.
Just have a look at Google and search for the store there. Google then also says whether the store is open.
Where exactly are you going to take this?
The best thing to do is to call the shop and ask.
But basically I think that it shouldn't be a problem.
