Right before the Golem from Prague

Right behind me, sometimes a clumsy man arrives at the synagogue, whose appearance and facial features are exactly like the portrait of the Prague Golem himself.
And decided to pray behind him.
And he prolongs his prayer excessively. And my feet ache…
There is no one to talk to, nothing to explain, nothing to ask for, because even in his mind he is like a golem.
What to do?
I thought the problem was when I knew the person praying was behind me, but is there an obligation to look?
I will finish my prayer before Connie and say 'I make peace' calmly.
Then I'll sit down too. Why look for trouble behind me?
