Wasting People's Time (Tircha d'tzibura)

You may not waste people's time or upset them (tircha d'tzibura).
Example A prayer leader should not:
  • Roll a Torah scroll during the minyan in order to get to the correct place for reading (it should have been done previously) unless necessary;  
  • Roll up his tefilin after taking them off for musaf on Rosh Chodesh, before hallel on chol ha'moed of Sukkot, or after hallel on chol ha'moed Passover. (Instead, he should take them off and leave them on the bima until the prayer service is finished, or roll them up during Torah reading).
