I was at the grocery store in line and the line was full so I left some room in front of me because I was standing in the walkway at that point and the store was busy. Some man gets in line behind me and tells me I should scoot up or else someone is going to cut in front of me. I didn’t say anything (idk why I always freeze) and moved up when the line moved. He proceeds to scoot his cart next to me as if he’s going to cut me off. Should I have said something about me leaving space for the walkway? I feel like it’s obvious but now I feel stupid for not saying anything and this isn’t the first time something like this has happened to me. It’s easy to say I shouldn’t let this bother me but it does because I feel like something is wrong with me
