Has anyone done this job at say a grocery store or Walmart, being an order filler for online orders (where people order online then come to pick up their order)? If so, does it have a lot of heavy lifting? I ask because I cannot lift a ton and just wonder how bad it is on lifting requirements. I've worked retail a lot before my current job, but never did this job before. Anyone who has can you describe what it is like and the pros and cons of it? Is it a good job for those with autism?
