Many employees are evaluated by "scan to scan," which is a literal count of the rate at which they physically scan ASINs and bin codes in sequence, so any activity other than that (including bathroom breaks) counts as a penalty against their rate.
Of course they also have multiple quotas for items per hour, based on item size and expected daily volume, etc.
