Restructuring And Related Activities [Abstract]
Separation Benefits	Note 17. SEPARATION BENEFITS As discussed in Note 2, we expect to exchange 17 of our 63 company operated sites for dealerized sites through the asset exchange transaction with Circle K. We anticipate dealerizing the remaining 46 company operated sites in 2019, and as such have communicated a plan to exit the company operated business. As a result, we recorded separation benefit costs totaling $0.4 million in the first quarter of 2019, which is anticipated to be paid by early 2020.

The entire disclosure for restructuring and related activities. Description of restructuring activities such as exit and disposal activities, include facts and circumstances leading to the plan, the expected plan completion date, the major types of costs associated with the plan activities, total expected costs, the accrual balance at the end of the period, and the periods over which the remaining accrual will be settled.
