...but my mum might be available some time

A little back story. I'm 19 but look about 2 years younger. Being a OK looking female (wow, way to toot my own horn there!) working in a locale where alcohol is served I get hit on. A lot. Last night as I was going on break one of my regular punters asked me out. Completely sober. He's in at least his mid 40s. I did what any mature, in control person would do in that situation... looked at him like he'd just set himself on fire, said 'No!' with a look of horror upon my face and then got out of there as fast as I could. A bit rude I know but my god, mid 40s. Sober! Shuddering, lots of shuddering.
