Yep, that's it, in the early days of the pandemic there was an emphasis on touch points, so drink fountains were out.In the early days of the pandemic lots of places removed self-service drinks, water fountains and even ketchup bottles as initial guidances was based on the risk of transmission via touch. Its only after the first year or two that those things were corrected.
If things remain closed off in 2023 its cost cutting, but in 2020 and 2021 it was definitly covid guidance done in good faith. They were wiping down coaster trains every hour even!
Now it seems rather petty not to bring them back.
