In act 4 scene 4, of Taming of the Shrew by William Shakespeare, how did Tranio distract Baptista for the evening?

Scene four takes us to Padua again, where Tranio and the Pedant (disguised as Vincentio), meet with Baptista. "Vincentio" grants his permission for his son and Bianca to be wed and guarantees Bianca a large dower. These claims prove satisfactory for Baptista, who readily agrees to the marriage, but decides against conducting the formal contract and agreement inside his own house, for fear that Gremio and his servants may be listening and might interrupt. Tranio offers his own house, noting that the banquet will not be a grand affair but promising a better one later on in Pisa. Lucentio and Bianca, meanwhile, on Biondello's advice, elope to be married post-haste while Baptista is with Tranio and the Pedant.
