This is a hotel keycard. It’s supposed to let you operate the lift and open your room door. Except it doesn’t always do that.
I’ve been in the Ramada Downtown for a week, and I’ve had to have my card “recharged” or changed four times. [Update: it’s happened five times in 10 days.] On the second occasion, the very pleasant check-in clerk told me I shouldn’t keep it in my pocket near my mobile phone.
But it’s not as simple as that.
