Here in Brazil elections are always on Sunday, vote is mandatory and everybody vote the same day. By 8pm all votes are counted and the result is known.
I always vote after lunch and it’s always empty. Because the vote is electronic, it’s very fast. I get there (we usually vote at schools too), show my photo ID (I use the ID app on my phone), use my fingerprint to unlock the voting machine, type the numbers and confirm, they return my phone and give a coupon to prove I voted and then I go eat a meat pastel and ice cream.
It has to have a person attached.
