They don't offer the refillable mugs or drinks per Orange Co health code. It doesn't allow Disney to take anything back over the counter. If self service machines were in the parks like at the resorts then it wouldn't be an issue, but that isn't the case. Even the popcorn buckets technically speaking aren't allowed to be done but a certain way. CMs we're trained to tell the guest to place bucket open on counter, then they will poor the popcorn in with a scoop withou the scoop coming in contact at all with the bucket. Then the CM is to instruct the guest to take the bucket, the CM cannot touch it. However I have heard from my friends at DHS that they have already been cited by the private health company Disney contracts for CMs not doing the process properly. It's all a bunch of politics...
