I frequently have to call people who are “too important” to respond to someone as lowly as myself, but my job is somewhat time-sensitive. In this case, I called Friday and was told this person had left for the day but would return my call this morning. I sent an email mid-morning and have not heard back by either. Planning on calling shortly, but I’m never sure when this becomes nagging.
(Dude is 9 hours away, I need to inspect the place this week...and he is presumably the one who instigated the process requiring the inspection)
