Well... I did have an answer, just not what you want to hear. If you can smell shit everywhere you go, it's time to look at your shoes cuz you probably stepped in some dog shit.

If my hotspot had a 5 minute delay, ALL my users would complain to me and to my coworkers. That sort of thing would not go unnoticed either by users or the staff.

99% of the complaints I do get are customer hardware/software problems and the customer ALWAYS thinks the problem could not possibly be on their end. I don't run a coffee shop but rather a full service IT department with thousands of dollars of diagnostic equipment.
