.. Okay, I am a "Cafeteria Supervisor." Ahem.
It is not brainless work, we have to adhere to ALL school regulations from the Department of Education and the State and the school and even have to know how handle seizures. And we have to, at that same time, keep stats on EACH class and for EACH grade and for all the children and Teachers. We make reports as well. And, we are not all just mean to kids for the heck of it.
We are not just watching the kids. Many times, with SO many kids in the cafeteria at the SAME time, we also... have to deal with kid problems and issues, the kids also tell us their problems or troubles with other kids, and we... have to trouble shoot that too and be a shoulder for them. We are not just standing there opening pudding cups or being babysitters.
Now, if that were me, I DO open things for the kids. Even if they are sick. They raise their hand, and we assist the children. Especially the Kinder kids. MANY times, they TRY to open it themselves, and it FLIES up in the air or slips from their hand and spills all over the child or the floor.
BUT, I will ask the child "did you try to open it yourself?" or I "teach" them how to open it. BUT also tell them, that if after they tried and they still need help, to call me.
Now, also though, I would not get so so mad... at that Cafeteria Lady, that told your daughter that. Maybe she is just a germaphobe. Or maybe she has Asthma or other health concerns... with which a cold would greatly impact her health. Who knows. Or, she could have called over ANOTHER Cafeteria "Lady" to assist your daughter.
There is no reason, to angrily confront the lady or make an argument about it. But in any school, there are MANY MANY MANY kids on any given day, that are sick/sniffling/coughing/sneezing all day at school and in the cafeteria while eating.
Sometimes, I even feel like wearing a medical face mask. Because, I... have... Asthma. And can get seriously sick, if I even catch a cold. For example.
But I wash my hands, after handling a child's things, if they are sick. And I wash my hands, OFTEN, while in the cafeteria. It is simple hygiene.
I even will tell kids (who I notice are sick but still at school) "Johnny... remember to cough or sneeze IN your elbow... not on your hands and not on everyone else..."
