Being considerate towards the musallees

Q: Is it permissible for an unpaid Imam to regularly go on to the musalla one or two minutes late because he is performing the Sunnah of Zohar Salah? Should the Imam defer the performance of 4 Sunnah if he knows or it is obvious he will overrun by a couple of minutes? It may be the case that these one or two minutes do make a difference to the office worker who needs to get back to work at a certain time, though it may be argued that there are several other Masaajids in the area with different Jamat times. The timetable states a particular time for Salah and there are numerous Darul Uloom students and teachers that could perform Imamat if the regular Imam is late. Yes, the timetable may have the caveat that Jamat times may change according to circumstances, but this obviously does not mean one makes a deliberate habit out of it. If the Imam is mazoor, that is understandable. However, in such a situation, is it not possible for the Darul Uloom to appoint another student or teacher to do the Imamat? Please note there are 3 questions above all relating to the same topic. It is requested you answer all 3.

Selling an item before taking possession of it

Q: Salmaan owns a grocery store. Ismail phoned him and purchased a pack of long life milk from him. After concluding the sale on the phone, Ismail did not take possession of the milk but instead sold the milk to Bakr and asked Salmaan to deliver the milk directly to Bakr instead of bringing it to his store. Is it correct for Ismail to sell the milk to Bakr before taking possession of it?
