1. it's indicating an advance left turn on green (instead of an arrow). Cheaper than installing a four lamp signal. Gradually being phased out by LED 4 lamp assemblies.

3. Pre-mixed fountain packaging (in 18L cannisters) is being phased out by the bottlers in favor of post-mix fountain packaging (higher margins and easier to distribute). Post-mix packaging (plastic bladders of syrup) requires more complex CO2 dispensers and water lines that many facilities are not properly equipped to handle. As well, the local water lines may create sensory issues from residual minerals and organics with the fountain soda that canned or bottled soda do not have.

Glad you had a great time.
