I have had several experiences with inconsiderate people and strollers and ECVs. I don't mind them at all and they serve a great purpose for those who need them. But, I personally feel the people using them should be more aware.
I have a neurologically compromised, visually impaired DD. We are the ones who will do the accommodating and not expect others to accommodate her. She takes responsibility for herself. However, there are some little things that she has problems with. She doesn't walk straight. When in crowds, we hold hands or I walk behind her with my hand on her shoulder. Another one, she has to get down close to items in a store to see them. Once down, she doesn't get up as fast as most people. Movements in general are labored. Like I said, we work hard to accommodate this. We don't go shopping at peak times, I will get the items off the bottom shelf and hold up for her to see, etc.
All that said, there have been problems with entitled individuals and using their strollers as a batting ram on my daughter. She has been rammed into from behind and literally knocked down to the ground and ended up in First Aid with scraps and tears. She has been shopping and looking at something and yelled at to "MOVE" when someone with a double wide turned onto the aisle where she was looking at an item. This person kept yelling for her to move and kept ramming her with the stroller because she wasn't moving fast enough. We ended up in First Aid again with a lump and ice. Both times, CMs noticed the incidences and were extremely nice to my DD. I have not been aware if anything was said to the individuals.
I have a friend who is in an ECV. She is one who will put it on high speed and expect people to just move out of her way. She will yell, "Coming through" and just go through. As a consequence, I don't enjoy going with her.
I have an issue with people who take the attitude that they are entitled because, after all, they have spent a lot of money for their vacation. Well, we have spent just as much $ for our vacation as they have. Personally, I don't understand why they feel more entitled than us and we should just move out of their way.
I realize that there are many reasons why people need to use an ECV or a stroller. I have no problem. I understand that they are also taking personal responsibility and are doing the best for their situation or family member. Not a problem with me. Not an issue with me. I do have a problem when your sense of entitlement spills over onto either my DD or myself. Everyone needs to just work together and be understanding so everyone can have fun.
