The benefits of being long-sighted.
I'm short-sighted and my last pair of bi-focals cost B12,000 from Euro Optic on 2nd Road, opposite Royal Garden Plaza, believe it or not. My previous pair of single-focals from there were B8,000. The work and service there is very good, although it's not cheap and probably cheaper to get from your own country.
I used to have 4 glazed pottery-style ashtrays at home, the type you often see in the bars. I have a habit of falling asleep on the sofa and depending whether the cat is hogging one end of it, or not, my feet may dangle over the arm rest at the other end in close proximity to the side table where my over-flowing ashtray resides. Yes, Mr Clumsy has gone through all 4 of his glazed pot ashtrays being woken startled as each in turn has crashed to the ground when playing footsie in my sleep. In steps Mr DIY who have a set of metal plates in varying sizes, one of which is 10cm in diameter and costs 9 Baht. A perfect little ashtray, unbreakable, although one has a slight dent in it now. I bought four. Two still sit on the shelf under my sink, unused.
Mr DIY stores are very useful to have around. I've bought lots of odds and ends from them over time. I won't list any more items with a short story attached, otherwise we'd be here forever.
