Thank this lady for giving you heads up OP. But forget that story do this:
If its relatively busy you won't get caught (sometimes there is literally only 4 or 5 rooms filled which is harder) and what I'd do is walk in and go to the rooms and walk around for 5 minutes in the halls and then go back to the lobby and hit up the breakfast. THe staff probably won't know what you are doing if you don't bee line it for the food and act like you just went to your room. Just kill a few minutes out of site in the halls and then hit the buffet.
If you're hitting it on a day where the hotel is empty you're more likely to get caught. So don't walk in and go right for the food.
Rachy is a female and that is likely why she doesn't get caught. Hopefully you don't look scrubby and are just broke since I'd be pissed if I had to look at some dirty fuck when I was filling up my juice or coffee (always get that separately and use the bigger cups from the room) scumming the free breakie.
I spend 50 or so nights a year in Best Westerns across the US b/c I travel for work. I love Best Westerns I always go for those when on the road over a RedRoof or Holiday Inn. The breakfast is bomb. The sausages are the best ever. But I like it when they rotate sausage and bacon (some are sausage only and don't put out bacon ever.)
My butthurt is immense when I forget to wake myself up before 10am to hit the free Breakfast buffett (I think they fuck you and end it at 9am some of them too which is gay.) I don't like it when they prepare the food insight either.
I know a Best Western that gives you two free alcoholic drinks from 4-530 every day. Its in Tucson :).
