'Oh hey SMS guy, just ringing to tell you that everything is ok but the oil change you requeated will take a little longer than expected. I'll call you tomorrow'
Tomorrow comes, no phone call... A while later..
'Ah yes, sorry SMS guy but I'm glad you called, the work will be delayed again unfortunately as we found some unexpected bugs on the windscreen. Nothing to worry about, we'll deal with them as quick as we can and call you back'
Two days pass..
'Oh it's you SMS guy, sorry we're taking so long but there's no need for your tone sir, we're doing our best! I know it's unfortunate but we just want to make sure you're delivered your car back in satisfactory condition. One of the bugs left a nasty mark on the side panel, we're just applying some polish.. IT'LL BE ANOTHER WEEK!'
