Very Bad service

I am disappointed with the service from Engen garage Laezonia. I just left the garage without filling fuel and sadly I'm always filling up at Engen garages. I wasnt served at the garage instead they were selecting cars to serve first while I came there first. I ended up leaving and end went to Shell garage opposite where I was served right. I'm so disappointed Engen garage Laezonia it happened just now at 16h00 wednesday 29th July. Speak to your attendants to stop selecting cars. This kind of service is the worst especially if I'm always your customer. I'm really disappointed I've been using that garage for long now and worse I've been tipping the attendants. I left unserved today. I think it was the last time going there
