During my school days, on 7th November, when you went to a 7/11 store, you could get a free slurpee. It's been years since then.
Last week I came across a 7/11 store and I noticed a big poster, get a free drink with any purchase. I forgot about the 7/11 promotion. So I thought why don't I re-live my fun memory and get a slurpee. It had more ice than raspberry flavour, oh well. Complain if it's free!
