Could be that, could also be the people taking a long time aren't at least causing a bottleneck (assuming there arent two of them at the same time). So you have this situation like this: first person takes 10 minutes, while there are 9 waiting in line that take only one minute a piece. With one teller, average wait time is ~15 minutes. With two tellers, its now ~5 minutes.
Which is why it is highly annoying when there's only one worker at the coffee stand, and there's always this one jerk at the front of the queue who orders a latte when you just want a coffee. With two workers, the people who just want coffee won't have to wait 15 minutes for the lattee people
And I've also noticed a social effect, when people wait a long time it seems to reinforce how they perceive the eventual serviced, that is, they want more out of the interaction, so take longer. Which makes it the situation even worse
> there's always this one jerk at the front of the queue
Here in the espresso world, that’s not so bad. But the ‘vanilla oat milk decaf, and also a hot muffin with butter’ is tedious.
There is a roaster in Auckland that’s been there since the ‘80s. On the counter it says ‘espresso, flat white or fuck off’. Clear and concise. I like it.
