The compound sign "GAS-STATION" combines the signs GAS and STORE.
When doing a compound sign you typically should use only one
movement from each part of the sign. Normally the sign for STORE and
the sign for GAS (as in "gasoline") each use two movements.
Normally if you use just a single movement the sign GAS means "put
in gas," and the sign STORE means SELL.
When you use GAS-(gasoline) and STORE as part of the sign "gas
station" you just do a single movement for "GAS" and a single
"movement for "STORE."
