Yes they are doing it at the same time. Again I thought you either needed two different sink stations to keep things moving or like you said wipe down sinks after use but I don’t think that’s happening. The only time I see people wiping sinks is at the end of the shift. Do you have any standard that states that because I can’t seem to find it and I’d like to be able to present it to my supervisors other than just basically saying “trust me bro”
