The finding that the defendant claims is not supported by the evidence relates to testimony of a witness called by the defendant at the healing. At the hearing, the defendant testified that he was not satisfied with the plaintiffs job performance because of numerous complaints from customers about his refusing to check the oil in their engines, closing the station early and telling them falsely that the air compressor was not working when they wanted him to inflate their tires. Only one of those customers, however, testified at the hearing. She said that “about a year ago” she had gone to the gas station and asked the plaintiff to check the oil in her car, but he had refused in a very rude manner. The date of the hearing was August 14, 1996, and “about a year ago” would refer to approximately August 14,1995. The defendant concedes that the plaintiff did not work at the gas station after May 21, 1995. The commissioner’s finding mistakenly assumes that this witness was *72referring to a date “approximately one year before” May 21, 1995, i.e., May 21, 1994. One of the commissioner’s conclusions alludes to “questionable witness testimony” presented by the defendant in his “futile attempt to characterize the [plaintiff] as a poor employee.”
