Man with small terrier-type dog walks into the bar and orders a pint. "No dogs in here" is all the response he gets, so he leaves. Tries the next bar, same response. After trying the next few bars down the street, he is getting thirsty and a bit tired of being turned away, when he notices in a shop the sign on the door - "No doge (guide dogs for the blind excepted)". Aha. The answer hits him.
In he goes to the next bar, where he receives exactly the same curt response as before - "No dogs in here". "No dogs at all?" he asks. "Well", replies the bartended,"we do allow guide dogs for the blind". "But I am blind" says the man. "What?" says the barman, "guide dogs are usually alsatians or labradors". "Oh" says the customer, "what have they given me then?"
