I go for tills that have a person operating them; in addition to not having to deal with an automated till that is not fit fur purpose, person operated checkout helps to keep someone in a job.
Main supermarket I use is Lidl, in addition to its cheap prices, it only having people operated tills is another reason I choose to shop there rather than the (more conveniently located, quicker to drive to, better parking) other supermarkets in the town.
