i suspect some online customer service reps have perceived me as one for my strong words about how their company has messed up (i actually usually point how they could do better--often involves beta testing websites when 'updated' and utilizing tech properly to better serve people.
i haven't encountered either (but i live rural), my daughter gets a lot of both at the Motel where she works. Most of them get angry they can't get exactly type of room they want for price they want when they come strolling in the day/night they want it without having made a reservation. Or complain the Swamp Coolers not hooked up when night temps still going below 45; or that TV isn't working. 1) The sets there actually tell folks that 'inclement' weather can disrupt service and often they checked in because that weather was too extreme for them to keep driving, but apparently expect the clerk to climb on the roofs (the motel has two sections and satellite dishes) in the dark to brush still falling snow off the receivers. 2) often the set is simply unplugged--same happens with other appliances in the room too. Nor can they wait a few minutes for hot water to travel the width of some 8-10 rooms from water heater pushing the cold water sitting in the pipes out first.
Of late, being an old white woman, i have on occasion come close to telling someone who apologized to profusely for blocking my path or accidentally bumping me in a crowded store that they need not worry--i'm not going to go all 'Karen' on them, but i usually just smile and say 'It's alright, accidents happen.'
