[Avodah] A better answer

[Rich, Joel]

R' Steinsaltz in a footnote in Horiyot mentions a tosfot in Shabbat that
opines that the gemara will sometimes ask the same questions twice
because maybe a chacham has a better answer.
Before I search every tosfot in Shabbat, does anyone know where in
Shabbat this tosfot might be?
