The time it takes to serve a customer at a bank is typically positively skewed, meaning that there will be a few customers who take a very long time to serve, while the majority of customers will take a shorter amount of time. This is because some customers may have more complex transactions or require more assistance than others, which can increase the time it takes to serve them. Therefore, a positively skewed distribution such as a lognormal or gamma distribution would be a good choice to model the time it takes to serve a customer at a bank.
