Asking for U Bolts

Many times I’m waiting for my daughter outside the school till she finished her class. There are two places wherein parents and guardians are allowed to stay in the school while waiting for the kids. I don’t stay there instead staying in a food store besides the school; actually the food store is a house itself. Anyway, one day while talking to the employee of the said food store, a man came and asking for u bolts. I’m not familiar with this tool but I learned from the employee that her manager was currently having a project at the back of the house. Well, I didn’t ask for more and just returned to what we were talking earlier.
