So im 21 in april, and i work in a bottleshop, and theres this hot as fuck older lady(40ish) that comes into my work and is flirty as hell, and calls me "darling" and "sweety", but im not taking them as ioi's. She is very chatty, and today she came in when the store was lonesome... she was a bit wild, and a little bit drunk, i asked her what she was getting upto, she sed she was having a quiet one, i teased her a bit and said she was boring... and she said "I dont find it boring, its only boring if your boring..." she was saying things like "what are you doing tonight??!, going out.. pick up some chicks " and waving her arms around....
Shes been in before, only recently have i started serving her(twice before) and shes picked up on chatter each time.... my question is what your opinions are on how i go about breaking the ice

attempt to number close this chick, if you get the number it Will be a major ioi. .. then text her by saying this

im at so and so bar , you should come along, its
fun.
Never call it a date, and the sentence i
gave u is even more casual then just
asking out.

it Will all fall into plan

Yeah i was thinking of going with the "Hey, if your ever out should catch up for a drink, give us your number!", solid?

yeah its certain to work, if there is even a minimum interest in you
