This study was carried out to investigate the effect of malodor and VOCs reduction that could be achieved through the installation of a vapor recovery system (VRS) in a gas station. It was revealed that the reduction efficiencies of malodor by running VRS were about 93% around the oil feeder, 32% in the office and 45% in the site boundary. Specifically, it was remarkable that reduction efficiencies of BTEX over 90% were recorded through VRS operation. In addition, the results of continuous monitoring of THC around the oil feeder device provided good evidence of the inhibition of oil mist diffusion after running VRS.

This study examined the relative effects of weekly and daily group feedback on the customer service behaviors in a gas station. Participants were four employees providing full services to the customers. Four target service behaviors, which were identified from the job description for the employees, served as the dependent variables. The data were collected by a supervisor. The independent variable was the frequency of group feedback on the four service behaviors: weekly and daily group feedback. An ABC within group design was adopted. After baseline (A), the weekly group feedback condition (B) was introduced. In the next phase, the daily group feedback condition (C) was introduced. Both weekly and daily group feedback were presented in a graph form and posted at a conspicuous location. Results showed that both weekly feedback and daily feedback conditions were effective in increasing the target behaviors. And, there was difference in the effects between the two conditions.
