Walking into the office, and there was a young lady who appeared to be in a hurry. She got to the door well before me and I would say I was clearly outside the 'hold the door for the next person' courtesy zone as I was still 15' or so away. She stops and holds the door. I continued at my same pace (rather than speed up) over the remaining distance while she remained holding the door. I told her thank you, but she was clearly put out by the delay. My thought is I was clearly outside the zone of door holding, and even if I hadn't been, you choosing to be courteous does not create in me an obligation to hurry no more than someone looking down at their cell phone as they walk creates in me an obligation not to run into them if they veer into my walking lane. Thoughts?
