I once worked for two hours out of a mc donalds, even had a 30 minute teams meeting (it was completely empty at 10 in the morning) and the wifi was quite fast
Wherever my internet at home goes out, the McD down the way is my "office." Hasn't happened in 5 years or so, but I've had to do it 4-5 times over the years. Take customer calls, write code, have team meetings. Works fine, and the $1 coffee ain't bad.
The Internet is good, and it’s quieter than a Starbucks. Back when more McDonald’s had 24-hour lobbies and my work habits were worse, I’d head over there to get a black coffee and ice cream to program or write.
