I live in an apartment and occasionally maintenance wants to fix something or change something in my apartment. This is fine since they give me 24 hrs notice and a time frame for when the worker is coming. However, yesterday maintenance had a person come in to regrout the tiles in my bathroom. The bad service is that the person used my toilet and didn't flush. I came home to find a nice big one in my toilet. The worker had also left the bathroom door open even though I have a large notice on the door requesting that it be shut (I have cats and I don't want them getting behind the shower; it's a pain in the arse to get them back out). I complained to maintenance and they said they couldn't really do anything about it but will talk to the worker next time they call him out.
Not so much bad service as EW service. He did do a good job on the tiles though.
